So today I went and bought some jeans and had a conversation with a saleswoman for awhile before and after I bought them. I was pretty attracted to her, but I couldn't tell if she was into me or just trying to make a sale. Our conversations did continue much after she sold me the merchandise and had nothing to do with pants. I concluded by saying that I would make sure to return soon and she quickly told me that she was moving stores in 3 weeks, so I should make it sooner or later.

All of my relations, while plentiful, have been with girls I already know or friends of friends, so I have a hard time telling if "random" girls are into me. I didn't think of asking her number, and I made the mistake of forgetting her name, but I would like to see her again. All I have is her Sales Associate number on my receipt.

How would you try to re-approach this girl without looking creepy-ish (i.e. standing outside the store everyday to see if she is there) or do you think she was just trying to reassure some sales and I shouldn't waste my time.
