Gah, more honest than me, I probably would have kept it. :) Back when I was more honest than I am now I had a woman at a grocery store give me too much change(not as much as you; I paid with a dollar and got change back for 10) and she got irrate with me and insisted she was right and made me take the money. She probably would have gotten fired for her till being under though, so nice of you to give it back.
