Once, there was a small hotel's owner who always cared about money.
One day, a businessman arrived at her hotel. The owner looked at the man's thick wallet and thought, "Oh, I wish that all the money could be mine!" The businessman ordered the most expensive room and went to his room to dress for dinner.
Around the hotel, there were some ginger(姜) plants. Many people said that eating the buds(芽)of ginger would make a person forgetful.
The owner thought, "If some buds of ginger were served 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 owner was very excited as the dish was served to him. "Delicious!" said the man. When dinner was finished, he went to bed happily.
In the next morning, the owner saw the businessman leaving from the front door. As soon as he was out of sight, she ran up to his room. She looked all over the room for the wallet, but couldn't find it. Suddenly, she noticed a piece of paper on the floor. It was the businessman's bill. He didn't pay it! She ran down the stairs, out of the front door and across the - road until she was out of breath, but the businessman was already, far away. "I'm so silly!" cried the owner.
