An English traveler found himself in Norway（挪威） with only enough money to buy the ticket for his journey back home. As he knew that it would take him only two days to get to England, he decided that he could easily spend the time without food. So he bought a ticket and went aboard the ship. The man closed his ears in order not to hear the sound of the lunch bell. When dinner time came , he didn't go to the dining room, saying that he was not feeling very well.

    The next morning he still didn't have breakfast and at lunchtime he again stayed in his room.But at dinner time he was so hungry that he went to the dining room and ate everything the waiter put in front of him. He got ready for a quarrel.

    "Bring me the bill," he said. "The bill, sir?" said the waiter in surprise. "There isn't any bill. On our ship meals are included in the money for the ticket," said the waiter.
