I worked for a short time as a cashier  at a restaurant a few months ago. I also helped to clean up the tables when it was very busy. One night, just before  Christmas, I found a large black wallet on the floor near one of the tables. I guessed I should check it to find out who was the owner, but I was very busy at the time. And I imagined that if there was something valuable  in the wallet, the   owner would be back. Sure enough, an hour later a man came up to the counter   and asked if anyone had found a wallet. I asked him to describe the lost wallet, and after he described it exactly, I gave him the wallet. He expressed his thanks when I handed it to him. He asked me if I had opened it, and when I told him "no". At  once he opened it and showed that it had nearly $ 800 in cash . He took out a twenty-dollar bill and handed it to me and I was amazed at this. "A reward  for your honesty," he said and then turned and walked away. Thinking about it later, I began wondering whether I would have been honest if I had known what was in the wallet! I thought that if I had no way to find the   owner and no one returned to get it, I might keep it. But it also came into my    mind that I actually saved someone's Christmas plans by finding and returning the wallet. The good feeling it gave me was worth more than anything could buy. Which of the following is true?
The owner of the wallet found a twenty-dollar bill gone. The writer wasn't surprised when the man gave her a reward. Nothing in the wallet was missing. The man was very, very excited when he got his wallet back.
