I have lost money before also. But I have found money too...I really hate it when I lose it but always put it in the back of my mind that the person who finds it probably needed it more than I did. I know the few times I have found money (1 or 2 bucks) on the ground it made me feel a little better for the day...50 bucks...I am not sure I would feel as good since I would be wondering who lost it and how much they may of needed it.
Believe it or not I have driven as much as 4 miles to return change to a clerk at a local convince store who gave me change for a 50 instead of a 20 (that I gave her) when the new 20's came out. That would of be money out of her pay if I had not returned it, and they don't make enough already
