Last Sunday, I dropped my wallet on the ground. By Monday, I was starting to look into cancelling credit and debit cards, and what I'd do without a driver's license... and then it turned out a "Mr. Diaz" who drives a garbage truck found it, called the numbers he saw in it, and established contact with me. I got it back in time for work; nothing was missing, and he refused to even take money when I offered it to him.

It's a very nice data point.
