I worked for a short time as a cashier（出纳员）at a restaurant a few months ago. 71 One night, just before Christmas, I found a large black wallet on the floor near one of the tables. I guess I should have checked it to find out who was the owner, but I was busy at the time. Also, I imagined that if the wallet contained anything valuable, the owner would be back.
An hour later a man came up to the counter（柜台）. 72 I asked him to describe the lost wallet, and after he described it exactly, I gave him the wallet. He expressed his sincere thanks when I handed it to him. He asked me if I had opened it, and when I told him “ No”, he opened it right away and showed that it contained nearly $800 in cash (现金). 73
“A reward for your honesty,” he said and then turned and walked away.
74 I began wondering whether I would have been so honest if I had known what was in the wallet! I thought that if there had been no way to find the owner and no one had returned to claim（认领）it, I might have kept it. But it also came into my mind that I had in fact saved someone’s Christmas plans by finding and returning the wallet. 75 The good feeling it gave me was worth more than anything money could buy.
A．He looked quite worried and asked if anyone had found a wallet.
B．Later I thought about it again.
C．To my surprise, he took out a twenty–dollar bill and handed it to me.
D．So I didn’t return the wallet until the owner returned.E. I wanted to be honest, so I didn’t care much about money.
F. I also helped clear off the tables when it was especially busy.
G. For quite a long time I kept happy whenever I thought about it.
