A guy I know pulled a pretty good trick on his manager when he quit McD's. He was working the drivethrough. Water is legally required to be free. So he asks the customer if they mind if he puts 99 waters on their order, won't cost them a cent. They agree, he puts them on the list and the machine starts stacking the drivethrough window area with cups of water. He walks out.

Even at 5 degrees, the light snow overnight and this morning have made the roads pretty unpleasant. Commuting through St. Paul this morning looked like a minimum 30 minute delay, so I'm sitting at home now.
