I worked as an overnight cashier at a Walmart, and I HATED the first of the month!
2-3 minutes after midnight, all hell broke loose, as these "people" wheeled carts upon carts thru the checkout lines. I had one lady PILED (yes, I said PILED) so much onto the conveyor belt, it wouldn't move! I had to literally reach back about half-way down the belt, checking out items as I went, before it would move again!
Some had been in the store so long, their frozen foods had thawed!
UN-FREAKING-BELIEVABLE!
