After 12 Years Behind the Bar, These 9 Drinks Are Instant Red Flags for Bartenders

There is something almost poetic about what happens the moment a drink order leaves your mouth and reaches the ears of a bartender. In the span of maybe three seconds, that person behind the counter has already formed an opinion about your night, your temperament, and possibly your entire personality. Sounds dramatic? Sure. Is it accurate? Absolutely.

It's barely a secret that bartenders are almost always judging patrons based on their drink orders. After more than a decade pouring, shaking, and watching the full spectrum of human behavior unfold across a bar top, certain drinks stand out, not because they're bad drinks exactly, but because of what they reliably signal about the person ordering them. Some are safety concerns. Some are pure etiquette disasters. Some are just exhausting to make at midnight on a Saturday. Let's get into it.

1. The Long Island Iced Tea: The Original Red Flag

Honestly, if there is one drink that has earned its notorious reputation completely and utterly, it is this one. Despite its pleasing color and mix of both alcoholic and non-alcoholic ingredients, bartenders rarely assume you're ordering a Long Island Iced Tea for its looks or flavor. Rather, this cocktail order is considered an instant red flag and an indicator that you're probably not interested in having a nice quiet night out.

The cocktail carries an alcohol concentration of approximately 22 percent, far higher than most highball drinks due to the relatively small amount of mixer. That is essentially a glass of straight liquor wearing a very thin disguise. The National Council on Alcoholism and Drug Dependence reports that alcohol is a factor in 40% of violent crimes, and bartenders, who are often the only line of management on a busy floor, are acutely aware of that number.

With around eight ingredients, this drink is a beast to prepare, especially in a busy bar where bartenders are trying to push orders out as quickly as possible. As one industry professional bluntly noted, "No one is ordering a Long Island Iced Tea because they like the way it tastes." That about sums it up.

2. Flaming Shots: A Fire Hazard in a Glass

Flaming shots might look cool on Instagram, but they're a nightmare for bartenders and a serious safety hazard. These fiery concoctions might seem like a fun party trick, but they come with a host of potential problems that make them a big no-no in most bars. Think about that for a second. You are essentially asking someone to introduce an open flame into an environment already saturated with alcohol fumes and crowded with people who are, by definition, not at their sharpest.

Many bars and bartenders refuse to serve flaming shots due to insurance concerns. If something goes wrong, the bar could be held responsible, leading to potential lawsuits and a whole lot of headache. In some areas, serving flaming drinks is actually illegal due to fire code violations. So, while you might think you're being adventurous by ordering a flaming shot, you're actually putting the bartender and the establishment in a tough spot.

The risk simply is not worth the theatrical payoff. No bartender, no matter how easygoing, genuinely enjoys the moment when someone shouts "flaming shot!" across a packed house at 11 PM. It is a red flag that reads less like "fun customer" and more like "potential liability waiting to happen."

3. The Espresso Martini: The Exhausting Fan Favorite

The espresso martini increased its ordering growth by 50% through 2024, according to Coffeeness via Forbes. It is officially the most popular cocktail on the planet right now. The Espresso Martini claimed the crown for 2025, proving that the coffee cocktail craze shows no signs of slowing down. Here is the thing though: the more a drink trends, the more bartenders quietly dread it.

There is no real standard recipe, and because they are so popular, people are really particular about the one they prefer. There are so many things that can go wrong with this drink, especially when espresso can easily be burned. Add to that the fact that coffee machines require cleaning, and nothing is worse than someone ordering a round of espresso martinis thirty minutes before close.

You can barely go on social media without seeing these drinks, and any bartender across the U.S. is probably tired of making them. I think this is the fairest red flag on the list. It is not that the drink itself is offensive. It is just that ordering it tells the bartender you are following a trend, not a palate. And in an industry built on craft and taste, that distinction matters.

4. Sex on the Beach: The Amateur Hour Special

Made with vodka, peach schnapps, orange juice, cranberry juice, and crème de cassis, a Sex on the Beach "flags you as an unsophisticated, novice drinker." The name doesn't help with the sophistication, and because the drink is so sugary and dated, it's clear to the bartender that a patron ordering this is only there to get drunk.

The Sex on the Beach isn't the only cocktail like this. Drinks like the Dirty Shirley and Green Tea shots have the same effect. They all belong to the same family, drinks designed to mask alcohol so thoroughly that you basically forget you are drinking anything at all. That is not a tasting experience. That is a plan.

The drink has been around since the 1980s and really has not evolved. Ordering it in 2026 is a bit like pulling up to a restaurant and asking for a Blockbuster card. The era has passed. When you order these drinks, many bartenders will see it as amateur hour. Which, again, fair enough.

5. The Aperol Spritz: When a Trend Becomes a Cliché

The Spritz was one of the 10 best-selling cocktails at bars and restaurants in the U.S. in 2024 and is increasing in popularity faster than other top 10 drinks, according to NIQ. On one hand, that popularity makes total sense. It is light, low in alcohol, and easy to drink. On the other hand, its relentless dominance has turned it into something of a cultural shorthand for "I ordered this because I saw it on Instagram."

One of the most significant shifts in drinking culture from 2024 through 2026 is the aperitif revival, the rise of low-alcohol, bitter or herbal drinks meant for sipping and socializing. The poster child was the Aperol Spritz, but as we move into 2026, the spritz is evolving and spawning new trends. The drink itself is not the problem. The robotic ordering of it, without any consideration of what else is available, is what catches a bartender's eye.

Let's be real: when a bartender sees the same order come in for the fortieth time in one shift, the enthusiasm starts to fade. Some bartenders think whatever is having a moment in cocktail culture is a bit of a red flag because it sort of shows that the person ordering isn't that original. Harsh? Maybe. True? Unfortunately, a little bit, yes.

6. The Bloody Mary at Midnight: A Question of Context

The Bloody Mary is a beloved brunch staple that becomes a bartender's bane after dark. This savory cocktail is a prime example of a drink that should stay in its lane, time-wise. While it is a fantastic morning pick-me-up, ordering one at night can throw a wrench in the works of a busy bar.

Bloody Marys should only really exist during brunch hours. After that, the ingredients have been put away, and getting them back together for one Bloody Mary would be inconvenient. Think of it this way: asking for a Bloody Mary at 10 PM is a bit like requesting eggs Benedict as an appetizer before dinner. Technically possible. Socially strange. Professionally exhausting for whoever has to make it.

This cocktail requires an extensive list of components, including vodka, tomato juice, lemon juice, Worcestershire sauce, hot sauce, and a blend of spices. Each of these needs to be perfectly balanced to create that signature Bloody Mary taste. After brunch service, most bars have broken down their Bloody Mary stations entirely. Asking for one now signals either obliviousness or an impressive level of confidence.

7. The Deconstructed Cocktail Request: "Can I Just Build It Myself?"

Here is a scenario that plays out in bars with more frequency than you would imagine. Someone approaches, orders a margarita, and then asks for all the ingredients separately so they can mix it themselves at the table. When people ask for all the separate ingredients of a margarita so they can pour it themselves, it is annoying for so many reasons. You may not know what really goes into making your favorite cocktail, and you are also showing that you do not trust the bartender to do their job.

It is the equivalent of walking into a restaurant, ordering pasta, and then asking the chef to bring you separate bowls of raw noodles, sauce, and cheese so you can assemble it yourself at the table. Bartenders are true craftsmen of the cocktail, and asking to deconstruct the work is a direct challenge to that craft.

I know it sounds like a small thing. But consider what it communicates. It says: "I do not trust your skills or your proportions." After twelve years behind a bar, that message lands. It always does. Ordering a cocktail and letting the professional handle it is basic bar etiquette, the same way you trust a surgeon without insisting on holding the scalpel.

8. The Bar Mat Shot: The Hygiene Nightmare

An unfortunate shot that is currently trending is a "bar mat shot." Someone will request to drink the runoff from all of the liquid that accumulates on a bar mat over the course of the night, poured from the mat into a shot glass. This rather unfortunate shot is surely going to raise some red flags for your bartender, and rightfully so. It should also be noted that many health inspectors urge drinkers never to order this shot, for obvious reasons.

This one is less of a red flag about the patron's taste and more of a genuine safety concern. What accumulates on a bar mat over the course of a night is an archaeological record of every spill, every drip, every overpoured spirit from the past several hours. It is not a cocktail. It is evidence.

There is also the basic dignity question. No amount of liquid courage should make this seem appealing. If you find yourself requesting a bar mat shot, consider it a strong signal that it might be time to ask for a glass of water instead. Bartenders everywhere will quietly thank you.

9. The Angel Shot: A Red Flag That Could Save Your Life

This one is different from everything else on this list, and it is important enough to take seriously. The Angel Shot is a fictional drink that is actually a code invented to send out a signal for help to a bartender, server, or any staff member. Generally, a woman who orders this beverage is asking the employee to intervene on their behalf because the date they are on may have gone south quickly.

More and more restaurants are now getting out the word about ordering an Angel Shot if the need ever arises by posting messages in the restroom for anyone feeling pressured, harassed, frightened, or threatened by the person they are with. Many bars, restaurants, and clubs have adopted additional Angel Shot code words to keep women safe, which gives the staff member further instructions. For example, ordering the drink "neat" requests an escort to the car, whereas "with ice" means a cab ride is needed, and "with lime" means "call the police."

Bustle reports that up to 80% of women expect sexual harassment during a night out, which is why more and more venues are posting such instructions in ladies' rooms internationally. When an Angel Shot is ordered, every good bartender stops what they are doing. This is the one "red flag drink" on the list that demands an immediate and compassionate response, not judgment, not hesitation.

A Final Word from Behind the Bar

The bar industry is changing fast. According to Gallup, 58% of U.S. adults had occasion to use alcoholic beverages in 2024, a percentage not seen since 1996 and a decrease from 62% in 2023. People are drinking less, being more selective, and paying more attention to what they order. That shift is actually good news for everyone.

As of 2024, an all-time high 45% of Americans said moderate drinking was bad for one's health, which means more people are walking into bars with intention rather than impulse. That is the kind of customer that makes a bartender's job genuinely enjoyable. Not someone chasing chaos in a Long Island Iced Tea glass.

None of the drinks on this list are illegal. Some of them are genuinely beloved. The point is not to shame anyone for what they order. It is to offer a window into how a seasoned professional sees a drink order, as a tiny but surprisingly accurate piece of information about who you are and what kind of night you are planning. Next time you belly up to a bar, it might just be worth asking yourself: what is this drink saying about me? What would you have guessed?
