I'm home for college for break and went to a store with my friend who works there. He talked briefly to one girl who works there and oddly she started talking to me a bit too. I dropped stuff off to my buddy one day and she was nearby and I talked to her briefly. My buddy, I and some other friends stopped into his work another time to check his work schedule and she came by and started talking to me. I made a stupid joke and she laughed at it etc all my friends thought she was flirting with me. I'm not sure what he asked but my buddy talked to her when they had a shift together, she basically said she only kept teasing me because of my reactions.
all the times I did go in she got progressively more flirty with me too
apparently she is a bit of an attention whore all the guys at her work hit on her but I kinda tried to ignore her because I could tell that.
