If you need to clean the bills and re-print them, only your prints are on the bill. If the clerk hands the cash over to the security personell and the police check it for prints, they'll find yours, the clerk's, and the security guy's. Obviously nobody touched the money before you did - hence you didn't get it as change.
It's good to not have your prints on the cash - wear gloves while you make it and wear band-aid sticky parts on your fingertips when you spend it. |
