I see your point, Mintyy. Sorry OP.
No, there aren't 'free taxi's' to Hospital appointments, my PCT don't cover taxi fares, only bus fares, which I don't need covered as I have a bus pass.
No, the bus drivers DON'T have to ask, and even when I ask and explain, people refuse to fold. (And I hate having yo explain and ask, as it means revealing personal medical details and my DS3's personal medical details as saying "we both have disabilities, I can't fold, and he needs to stay in his wheelchair pram" isn't enough, as people expect to know why. And still don't fold 99% of the time , even after an explanation.
In our town, if you buy a return ticket and get off the bus to allow someone else on, you have to pay again to get on the next bus. And the drivers refuse point blank to wait while somebody folds their pram to allow me on, as they are always running late due to traffic, and they get in trouble for that, so they doing want to make themselves even later by waiting for someone to fold their pram.
Which is how my story relates, in part, to the thread - people are so rude now, that they won't even fold for people with disabilities when ASKED. So they're unlikely to get off a stop early to let the OP on.
And I pointed out that the comment was rude or rather thoughtless in as much that they expected the OP to have run for the bus in the same way that they would have.
Regular bus users tend to expect not to be able to get on the first bus that arrives at the bus stop if they have a pushchair or a wheelchair.
