My mate always used to complain when we were students and had a ten o'clock lecture as at 9.30 the OAP's used to get on the bus with their free passes. So it cuts both ways.
When BD was a boy we got the double decker BMMO buses up the hill to school, they were crowded and I was always scared that I wouldn't get chance to pay. Of coures I soon worked out that I shouldn't pay in any case, ie walk and spend the money on fruit salads, black jacks etc
By the time I left for secondary school the double decker had gone to a single deck, and by the time I left secondary school it had gone to a mini bus. I think a few of the poor kids now have a council taxi service. Good that the buses are still used in London
