George and his wife had a small bar. The bar often kept open until after midnight, because people came to drink there while they were waiting for trains. At two o’clock one morning, a man was still at a table in the small bar. He drank too much and was asleep. George’s wife wanted to go to bed. She went into the bar several times, and each time the man was still there. At last she said to her husband, “You have waken that man six times now, George, but he isn’t drinking anything. Why haven’t you sent him away? It is very late.” “Oh, no, I don’t want to send him away,” answered her husband with a smile, “you see, whenever I wake him up, he asks for his bill. When I bring it to him, he pays it. Then he goes to sleep again.”
