When an English traveler was to return home Sweden, he found that he had only enough money left to get a ticket back to England.He decided that as it was only a two days' journey he could get home without eating anything, so he bought a ticket with the little money he had left and went aboard the ship.He closed his ears to the sound of the lunch bell, and when dinner time came, he refused to go down to the dining room, saying that he did not feel well.The following day be did not get up until breakfast was over, pretending that he had overslept.At lunch time, too, he kept out of the way.By dinner time, however, he was extremely hungry."I can't stand any longer,"he said to himself,"I must have something to eat."At the dinner table he ate everything put in front of him.When he was quite satisfied, he felt stronger and called the waiter."Bring me the bill," he said to the waiter.""The bill?"said the waiter in surprise."Yes,"answered the man."On this ship meals are already included in the ticket."
