I tend to avoid McDonald's (apart from the staines one as that's not normally busy) and I end up travelling extremely early or late for cheap split tickets so stations aren't an issue.
I have in the past opted to wait till the next bus because of how packed it is (work were not pleased).
My point is I don't tend to have major issues unless something exceptional has happened (such as being accused of bringing a bomb in) or I end up stuck in a queue that seems to be not moving and packed in like sardines.
I don't have a carer because I don't need one, having someone with me isn't going to help if I'm packed in a queue line (and yes I have noped out of the queue before).
Basically if I don't need to interact with people I'm fine
the parks are exceptional case because it's my happy place so I do have a slightly higher tolerance then say McDonald's.
