LOL!!!!!! I did that all the time cuz the busses were so damn full and the lady collecting the money and giving the tickets either never got there in time cuz of so many people she couldnt move anywhere or I'de kinda move about avoiding her. Cant avoid paying for the маршрутка though. Oh, except someone I was with one time only had a 500 ruble note and the guy didnt have any change for it, and we got to our destination and just didnt pay. So we kinda caught on, pay with 500 rub note and get ride for free. alot of the time they did have change but sometimes not. or they'de just kick you out, lol!! I love Russia, It's such a great place!
BTW- its amazing how they drive and handle all the money coming towards them and getting all the change back to everyone while driving in those crazy Russian streets, esp in winter.
