I understand that but like it's retail , it's not serious at all and has nothing to do with the job i wanna doYou're 18 years old. I disagree with the guys above trying to distinguish between it being a "career" or a "job." It makes no difference. One wrong move and she reports you to HR. This kind of thing can follow you wherever you go and will be something you never live down career wise whether it is related to what you ultimately get a degree/expertise in or not. This is without even addressing the normal day-to-day headache which is much less serious but still problematic. Don't do it.
Get women somewhere else, brother. It isn't worth it.
