Why is this girl always making me wait at counter to put my coffee order in?

This girl and I have clicked so easily and she doesn't know me that well. I even took a massive gamble and added her on facebook and she accepted it. But I've noticed she makes me wait at the counter to take my order. Eventhough she isn't that busy and she knows my order. Why is she only making me wait at the counter all the time. She is still been nice to me too
