On a note about pressing against backs of seats. I find as someone that is over 6ft, the leg room on a bus is often unsuitable for me. So I have to sit with my legs to the side, otherwise I'd end up with pins and needles, where the leg room is affecting circulation. For that reason though, I try and sit at the front, despite OAPs pointing out I haven't got a disability. I'll excuse their ignorance for thinking all disabilities are visible.
