How do I ask out the cute bookstore cashier guy?

So there is this guy who works at the local bookstore that I frequent every now and then. For about a year now I have noticed him, but more recently I have developed a crush on him. I would like to get to know him and possibly ask him out on a date.

I am quite shy and tend to stumble on my words when nervous, and I really don't want to make a fool out of myself when approaching him since I want to be able to go back to that establishment in the future. I am also terrible with smalltalk.

So what do I do? I could ask for help finding a book or something, but any regular customer can do that; how do I show I am interested? Take it to the next level? From customer to possible date? I realize now that he won't be the one asking for my number since that would be a no-no, so it has to be me.

I should also add that I am in my late twenties and so is he. Sadly, the getting one of my girlfriends to do the asking as I did in HS is out of the question! I got out of a three year relationship recently and my flirting skills are a bit rusty! I only make eye contact but then shy away... lol. Help!
