I was shopping in a popular retail chain looking for jeans, and the girl that works there in the fitting room was very flirty/nice with me (though i understand they kind of have to be like that). We exchanged names but not numbers (it was really busy, and that it would've been bad to ask her out in front of her boss).

Should I do anything more? Could always go back, or just call the store asking for her... but all of that sounds creepy.
