Cute cashier?

Anonymous
I was at the grocery store yesterday and there was this cashier that I thought was cute (maybe others wouldn't, but I did). I know she's there to work, but I live in a small town and there aren't that many costumers, so I don't think I'd be much of a bother if I just started a conversation.

Even though I'm shy, I've started conversation with cashiers before, but they were in bookstores or clothing stores, and therefore conversations were a lot easier to start, because I could talk about books or ask for their opinion on some item there. The ones I've had conversations with seem to like me a lot and appreciate seeing someone familiar because the next time I go there, they always smile, go up to me and open a conversation by themselves (and more personal topics), but I have bad luck because they are NEVER single.

Anyway, I digress. I have no idea how to start longer conversations with a cashier in a grocery store, I can hardly talk about food! And asking about how it is to work in the store seem to be a rather short and impersonal conversation :-/
