Do you use the self serve checkouts?

It's like a contagious disease. Just left the AT+T store. Actually told me to swap my own SIM card. And "we don't transfer data to your new phone." WHAT DO I PAY YOU FOR? Customer service means give me your money and get out of here.
We're with verizon...thier store jerks, sorry, clowns, sorry, clerks are the reason the wife won't let me go in there anymore
