Also, wear your best push up bra and you know.... That kind of stuff.

You could tell them in a wobbly voice, "My boyfriend says he'll break up with me if I don't quit and I
need to do it." only do that with the female staff, if you dress up too much one of those male vape shop employees is going to WANT a breakup to happen. Or, you could say it as, "My boyfriend broke up with me because I didn't do what i said, but
i couldn't. That would be the time to cry, placing the vape equipment on the counter, then reviewing your troubles with the mod. LOL. Can we make the return videotaped? I'm fully vested in your problem, heh.
But in all seriousness, good luck at the vape shop.
