We're fast approaching the New Year's Eve big night out.

Do you think you'll be sticking to one particular drink all night - or will you mix things up and really go all out as you see in 2018?

Whether it's a gin and tonic, pint of bitter or a crisp Chardonnay, each of us has a go-to drink to help get us in the mood.

The chances are, when ordering, you've not really given your drink a second thought - but maybe you should, because you may very well be annoying your bartender.

And you wouldn't want to do that, would you?

So to help you help the bar staff this New Year's Eve , Business Insider spoke to Elena Alvarez, bartender at The Airliner in Iowa.

1. Long Island iced tea

Not for the faint-hearted, with their multitude of ingredients, Alvarez says requesting a drink like this takes a lot of time and is one of the most annoying things to bartenders.



The two most complicate drinks - and therefore most irritating - are 'real' Long Island Iced Teas, with all four or five kinds of liquor in them, and Bloody Marys, with all of their garnishes.

2. Mojitos

There's a legend surrounding mojitos, as one bartender explains : "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."

Apparently anything involving more than two ingredients which is served in a martini glass is a real pain to make.

So maybe go for a beer instead.

3. Margaritas


4. "Surprise me!"

According to Alvarez, indecision is EXTREMELY irritating.



5. A Guinness

...But only if you order it last. A Guinness should always be ordered first, as they take a while to pour.

6. A Manhattan

Revellers are urged to do their research with these, as another fed-up bartender says: "Either people order one because they're trying to be sophisticated and don't know what they're getting, or they aren't specific enough and it doesn't end up tasting like they wanted."
