Back last fall, I did a little work for a very large textbook and educational materials company, but was never paid. The person there I was working with stopped returning my emails and calls a few days before my deadline. After a month or so, I finally gave up. I even thought about ranting about it on my blog a few months ago. And then today, I received a check in the mail from this company for the full amount, about half a year late. At this point it's practically free money, because I had forgotten that I even did that work for them, and didn't figure that it was worth the $250 to try to work the red tape any longer. So, yay.
