That's my motto. I've been in situations when a new worker is taking longer than usual, but you know what? You wait. I even thank them and say have a good day. Everyone has been new at a job before. Everyone. I don't know... I've dealt with delays and issues out of cashier's hands several times and know how it goes. My register is a computer screen and loves to freeze and shut down when I do returns sometimes. It sucks. Also, fuck customers who complain to me about prices. Bitch, I don't set them, haha.
