How long do those lemons and limes REALLY sit out? BuzzFeed talked to real bartenders to find out their secrets, tips, and tricks for getting your booze on.

Get served more quickly in a crowded bar by flashing your cash. Maybe.

"Have your card or cash in hand and visible so I know that you're ready to order. If you're looking over your shoulder and still trying to get your friend's drink order then I move along to the next customer."

"Do not try to get our attention. At all. We know you're there, and we know the order in which people got to the bar. We know you want something. That's why you're at the bar. Do not wave. Do not yell."

"Honestly, the best method is to be obviously ready to order without asking a ton of annoying questions. Don't worry, if they make eye contact, they'll get to you. If you wanted to not wait for a drink, go to 7-11."

Don't send a drink back — just don't.

"Unless it is entirely the wrong drink, do not send it back. if your martini needs a 'smidgen more olive juice,' then shut up. Make it yourself next time."

"Have your friend drink it."

"If you complain so much that the bartender takes it back to shut you up, but then don't expect anything resembling good service for the rest of the night and/or any other time you come back. Bartenders remember that crap."

Eek — the glasses aren't always as clean as you'd hope.

"If you see the bartender cleaning glasses in a sink, or, yuck, using a bar towel to dry them, drink something that comes in a bottle or can. Frankly, if you see a bartender use a towel for anything except the drying of clean hands, run away."

"Wineglasses and champagne flutes are harder to clean. It's easy to miss lipstick or chapstick on the edges, because you have to wash them more gently than you do with a pint glass.

"The best way to tell if your glasses are clean is to look at the lacing as you drink your glass of beer — basically, does the head kind of stick to the side as you drink it, making little rings around the glass as you drink it? If it does, you've got a really clean glass."
