Craig - why does she always spot you upon entering? Has she caught you staring - or have you had a conversation with her?
She is probably bored working in a place like that. Ask her if she ever wants a TV -plugged in so she can follow the Oscars or the NCAA tournament. You are only mere steps away from being able to say something subtle like, "I should buy you and your friends coffee or something whenever your shift ends."
By 'friends' you will imply co-workers to her. But in your mind 'friends' will mean her left one and her right one.
