   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. （1）
   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 B was the owner，but I was busy at the time.I imagined that if there was something valuable in the wallet，the owner would be back.（2）Sure enough，一小時(shí)過(guò)后 a man came up to the counter and asked if anyone had found a wallet.I asked him to describe the lost wallet， （3）He expressed his thanks when I handed it to him.He asked me if I had opened it，and when I told him "no".He opened it at once and showed that it had nearly ＄ 800 in cash.He took out a twenty-dollar bill and handed it B me and I was amazed at this. "A reward for your honesty，" he said and then turned and （A）walked away. （4）
   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（A） giving back the wallet.The good feeling it gave me was worth more than anything could buy.
