Once there was a small hotel keeper who was always caring about money.
One day, a businessman arrived. The keeper looked at the man's thick wallet and thought, "Oh, I wish that all the money could be mine!" The businessman didn't notice that, so he ordered the most expensive room and went to his room to dress for dinner.
Around the hotel, there were some beautiful ginger（姜）plants. Many people said that eating the buds（芽）of ginger would make a person forgetful.
The keeper thought, "If I serve some buds of gingers to the businessman, he may be forgetful to take his wallet!" Then she went into the kitchen. Soon, the businessman came downstairs and asked for dinner. The keeper was very excited as she served the dish to him. "Delicious!" said the rich man. When dinner was finished, he went to bed happily.
In the next morning, the keeper saw the businessman leaving from the front door. As soon as he was out of sight（在视野之外）， she ran up to his room, She looked all over the room for the wallet, but she couldn't find it. Suddenly, she noticed a piece of paper on the floor. It was the businessman's bill（账单）. He had forgotten to pay for it! She ran down the stairs, out of the front door, and across the road until she was out of breath（上气不接下气）， but the businessman was already far, far away. "I'm so silly!" cried the keeper.
