As a kid I was at a public swimming pool that also has a concession stand. I had the money my mom gave me in the pocket of my swim suit. She had received them from her bank the day before. They were new $1 bills with consecutive serial numbers. I had been in the pool earlier but had been out long enough that my suit was dry but the money was still a little damp. As I was presenting the money to the cashier, I told her that it was good and that I had printed it up that morning. She refused to take them.
