"I have the right": Payment of tickets in public transport

zdravstvuyte, "MK-Sootechestvennik"! Thanks for your newspaper. Never thought that I will face discrimination in Germany, but the fact remains. My car is on repair. The travel card because of two days of trips on public transport did not begin to buy. Jumped into the bus, and there the cash desk is not present. The ticket should be bought from the driver. It costs 3,60 euro, and I have no trifle. I give to the driver of 20 euros, he answers me that he has no delivery. I explain to him that I have no small change. And it to me: either pay, or leave. Grannies began to be whispered supposedly on belongings money is, and on the ticket is not present! It is a shame...
