Eric Zorn has a more positive story than my own posted earlier today:
Somehow, I dropped my Visa card on the way out of the grocery store after running a quick errand this morning. When I discovered it missing two hours later, I performed a quick, fruitless search then called the store.
They had it. I'd somehow dropped it by the door on my way out and a customer had picked it up and left it with a store employee.
Very nice, but not surprising. the rest
