they really dont do any of that stuff.... if they drive away its cos u didnt get there on time, and not all of them do that!! they dont wana keep the bus waiting because people may be in a hurry and have already waited ages for the bus, and depending on how far away u are, its simply not fair.
They have to keep change otherwise if someone gets on witha ten pound note wont be able to get on, as there wont be any change. Everyone pays with pound coins so they end up giving out laods of 80p change, and its not as if they have a spare change safe somewhere, what they have with them is all they have. sometimes they have to give their own change iv seen it. If someone doesnt look old enough then its their job to ask them to provide id! its that simple, so many kids try to get away with trying to be younger than they are - me for one! its just their job, theyr really not that bad.. and if they do act a bit stressy, can u blame them? theyv been driving a bus all day, the same route for like 9 hours...its not exactly exciting.
