Call me a desperate housewife, but I love watching my total go down on the grocery store cash register. I always wait to swipe my card at the end so I can see the numbers roll down all at once. It's like a Vegas slot machine without the bells and lights. Also, I'm one of those annoying shoppers in line ahead of you who insists on handing over a stack of coupons just to prolong your impatient agony. Sorry! Our grocery store doubles them too. WooHoo!
