Have you ever...

...run into Wal-Mart to pick up a few items and decided to check out in the garden center because it should be faster only to find yourself behind a woman with an overflowing buggy of games and dvds and makeup and foodstuffs who waits until the cashier rings up everything in said buggy to announce that she only has $12 and must have the cashier unring items one at a time until she brings her multi-hundred dollar bill down to $12.10 because she just can't live without anything that would bring her down to the $12 that she actually has so she starts calling people on her cell to bring her $0.10, which you could give her but by that time you are so mad that you want her to have to wait for someone to drive a dime over?

I have.
