Glad to hear you still think fondly of your time there, yes stuff happens, everybody makes mistakes.If you do not wish to work so much with customers, maybe try maintenance, or night crew. Most stores desperately need overnight stockers. Just say no to front end! You will quit within a week if you choose to work the front!
But yes, this is what I was wondering, I've been a cashier and can't do it anymore, people are just too much for me.
