Expired booze
As you can probably guess, cocktails aren’t exactly the healthiest beverage available. But since night clubs focus primarily on getting you drunk out of your mind, and you’re there to get drunk out of your mind, nobody’s counting calories, right? But if you don’t want to risk your health while killing brain cells, you should stay away from the less popular mixes.

Odds are that the ingredients that go into the worst sellers are probably expired already. And since these drinks don’t fly off the shelf, so to speak, night clubs aren’t going to update its inventory. It’s not worth the cost.
