An artist, who was very kind but not rich, was coming back home by train one day. He didn’t have any money with him, because he had given all coins he had to a beggar. Afterwards, he found another beggar and asked him if he would like to go and have lunch with him. He accepted, and they went into a small restaurant. But the artist forgot about the money, and in the end the beggar paid for the lunch. The artist, embarrassed, wanted to give him the money back, and invited him to come by taxi to his house. The beggar refused the purpose, and told him he wasn’t going to pay for the taxi home.
