You walk into the foyer of your building at work, and see a 3/4 full packet of chewy on the ground. It looks slightly dented, but apparently untainted. Do you:
A. Dionne Warwick it, and Walk On By. You wouldn't stoop so low as to eat some random gum from the ground. Germy. Disgusting. Sneer.
B. Leave it. It doesn't belong to you. The owner might be back to reclaim it.
C. Finders keepers. You look to see if anyone's looking, pick it up and pop in your pocket for safe keeping and latter enjoyment.
