One day, a man went to a barber shop for a haircut, but he didn't know which one to go to. At this time, he saw a sign in a barber shop that said: If the barber shop shaves a few knives on the guest's face, please treat him to several meals, and customers who go to the shop for a haircut will be rewarded. So he went in, looked like a master and thought it was ok, so he sat down and let the barber cut his hair. On the way, the barber accidentally cut a long hole in the man's head. The man said you would invite me to dinner, and the barber agreed, and then he was accidentally scratched. The man said that you would treat me to dinner twice, and the barber agreed. Later, the barber shaved the man several times, and the man said that you invited me to dinner for a few days. Finally, the barber was angry when the man said he was old. He said, OK, I'll keep it.
