I find that its the young people, who appear very healthy, who use up he seas which are meant to be for disabilities, pregnant women etc They then pretend they can't see you, or even, once I asked a teenage boy of around 13 if I could please have his seat, he said "no, I've got a bad leg" and refused to move, he just sat there and laughed. At least when we had conductors on buses they would have made him move or get off the bus
