Like the Seinfeld joke:
Why is it that some people can't count to ten, but can count their $48 in change, if their bill is $52, and they gave the cashier a $100 bill?
I would love to see a cashier send someone to the back of the line with more than 10 items in their cart.
How rude and inconsiderate of others. I am talking about people who think nothing in getting into the ten items or less, with 25 or more items in their cart!!
I was informed by a manager, "well there was no one in that line!!! If I was his boss, I would have had a talk to him about customer service.
