This past weekend I went shopping for a bunch of things, one of which was a pair of shoes. The sales person rang up my credit card but apparently hit the wrong button. The register read my card number as the amount of a travelers check. The register read that the store owed me change of $32,000,000 (rounded). I took it in stride and patiently waited for them to load up a few suitcases of cash which would allow me to be on my merry way before they would notice their error. Unfortunately, that didn’t happen and they made the correction.
That leads me to another personal finance question though. What happens if you are at a register, give the guy a $5 bill and he thinks you gave him a $20. You end up with change far exceeding the amount you gave to the guy (or girl). What is the right thing to do? Accept it as free money? Give it back to the guy and let them know their mistake? Does it matter if the error is a huge amount of money or if its just a tiny sum?
