• We spoke to bartenders to find out what drinks they hate making the most.
• Sometimes the simplest drinks can be the most annoying to make.
• Whatever you do, don't say "surprise me."

Everyone has a "go-to"drink order, whether it's a gin and tonic, a whiskey sour, or a Long Island iced tea. But what if your favorite drink is secretly irritating the bartender?

We spoke to Elena Alvarez, a bartender at The Airliner in Iowa City, Iowa; Chelsea Jenssen, a bartender at Tao Downtown nightclub in New York City; and heard from various bartending Redditors to find out what drink orders irritate them the most.

A Long Island iced tea

Alvarez said requesting a drink that takes a lot of time to make during a big rush is one of the most annoying things to bartenders.

"The really difficult drinks with a lot of ingredients are always annoying to make when things are really busy," Alvarez said. "Do you see how many people are crowding the bar right now while you're asking me to make something for you that's going to take a few minutes? That's really annoying."

Alvarez says two of the most complicated drinks to make are 'real' Long Island Iced Teas, with all four or five kinds of liquor in them, and Bloody Marys, thanks to all of their garnishes.

A mojito

"I've heard it said that the person who created the mojito must have hated bartenders because it's a complex cocktail that takes a long time to make, and making one leaves your hands all sticky. If you want a bartender to hate you, order a mojito when the bar has a long line," said SnowHesher. 

Jenssen agrees, adding that "Mojitos and anything with more than two ingredients or that is served in a martini glass is annoying to make." 

According to Mackin-N-Cheese,"Mojitos are a pain in the a**. It takes time to muddle the mint properly, the sugar and fresh lime are sticky. Honestly, if it was busy, sometimes I'd just say, 'Sorry, we're out of mint' so they'd order something else."

A margarita

"A margarita is super easy to make, but it totally messes up my flow because shaking the drink for 20 seconds is annoying when I have 100 people waiting at the bar," Jenssen said.
