Mary was a pop star. She bought new house, and hired a man to painting the rooms in new colours. It was difficulty to get tickets for her show, because of everybody wanted to see it. So she decided to give the painter two of the best seat. She hoped that this would make him to work better. He took the tickets without saying something. She hears no more about him until the end of the month, then she got the painter's bill. On it was the words: "Three hour's watching you sing and dance: $ 6. After 5 pm I get two dollars an hour instead of one dollar."
