Should I go to see if he's there, I do it every weekend..?

My crush works on the weekends in a place that I shop at. I go there almost every weekend just to say hi, and to see if he's working. I'm thinking I am now sounding too desperate..... I mean I BUY stuff too, but I make an effort to say hi to him.. and If I don't he'll call my name and say hi to me..... tee hee. Well should I go this weekend, or just not go and leave a parents to go shopping instead of me?
