I worked at a Gap store and it's a fun place to work and made some cool friends while I was there. Most sales associates don't stay very long. It's not a very high paying job but I think it's a good part time job if you're a student. Oh, and unlike certain other retailers catering to young people, diversity is welcome and encouraged.
I can't remember exactly what I made but it was around 6 dollars an hour.
