I just had a joke.I sit in the bus at the end, we load. By the way, travel in our bus n-new route 5 UAH.for pensioners and on certificates -free. The bus is already full, almost the last man enters, presents a certificate and passes to the last door. This character returns to the driver, says - oh, I confused the bus, return the money. He gets $5 and goes on with a smile on the street.
