do you get another receipt? I didn't and the person just accepted my package. I am just being paranoid here probably, but isn't it easy for the person to steal my package since there's no proof of receipt? I have the tracking number since it was prepaid online. I kept checking it but my package hasn't been proccess. Any idea what's going on? (first time dropping a prepaid package at ups store). sorry if this is a dumb question. thanks
