Does this girl like me or not I'm confused..?

That's quite cute, I think she likes you, but she doesn't want to feel that way possibly because she is afraid of rejection. I feel the best thing to do in this situation would be to start some light hearted banter, perhaps be a little cheeky and intreigue her. Then when she feels herself start to enjoy your company a little, tell her she looks nice, wait and see her (probably slightly awkward but cute reaction) then send her a friend request on facebook. When she starts warming up to youa few shifts later, ask her if she would like to hang out with you sometime.
