Chill out man. Don’t blow this up into something it isn’t. You are going to let one interaction define you as a person?
You made a few mistakes. Learn from them and learn to laugh it off.

Go to some other places to buy your food and when you go back, stop staring at her. Instead smile and wish her a good day like it’s no big deal. More importantly, you are in college. Go drink some beer and chat up some other girls that aren’t working in a place you frequent 3 times a day,
