What really gets me is none of these people working cash registers know how to properly count back your change after a purchase. They just hand you whatever the machine tells them. Back in the day if you couldn't count back change you didn't work the cash register. McDonalds got the stupid started by putting pictures on the register keys instead of #'s. All downhill from there.
BTW: by counting back the change properly I mean if your purchase is $12. 75 and you pay with a $20.00, the cashier gives you a quarter saying: "25 cents makes it $13.00 $2.00 makes it $15. 00 and $5.00 more is $20.00. Have a good day."
