You get the hang of it. I worked as a barback at a chain of benihanana called RA sushi and had to memorize all of their custom drinks which is a large list. The bartender there helped me out every step of the way. It's a given that you'll fuck up at first.

Barkeep I'll have 3 fingers of Red Eye! LOL
Relax you'll do just fine. Most bars have a Pink Elephant book if you have to look up how to make a drink. By the way if a guy comes up to the bar and asks you for a Blowjob, that is a drink, so is Sex On The Beach. LOL
