Dh has started to steal from self service tills. Mostly small items such as chocolate bars or cans but today he came home with a new wallet! He bragged about how the wallet was free. He has also on occasion come home with blind bags for ds. He'll pay for one but take 3! I basically told him he was shoplifting and we had a big argument over it. He said "everyone does it" and that I'm no better as we were under charged in a restaurant once and we didn't say anything. I told him he could easily be caught but he doesn't see the big deal in it. AIBU?
