London Transport used to have a by-l;aw requirement that an orderly queue was
required for boarding a bus.

I know it might be irrelevant for all intents and purposes, but I can't help
feeling that abolishing the by-law was a retrograde step and sent out all the
wrong messages about what is, and what is not, civilised behaviour, at a time
when many people haven't the foggiest idea of how to behave.
