Repair computers at home. Called the client, said that the problem was solved and he could come to pick up the system block. When asked how much, he replied that 750 rubles. In three hours he arrived. He gives money and says, "There are 700 rubles, no more, 50 rubles later." Okay, but don’t forget, I say. The money was not counted, and it was already dark. At home I counted, it turned out to be 1100 he gave me - instead of 100 accidentally put 500. I don't need someone else, I still owe 50 rubles, I think, when he gives, I will return him more. However, half a year has passed and still does not give a half-point. It was expensive.
