Well, that's kind of my point. Most bus-stops are just a free-for-all, which is rather a shame (and as commented on recently by Lost Yorkshire Man, it's not a universal approach, but a new London approach). But in the station at London Bridge, there is a great example of a very fair and self-regulated queueing system for an incredibly busy stop where hundreds of people get the bus in a really short period of time. So it's extra annoying that people jump in. I'm going to go and lie down now, as I'm embarrassed that I've ranted about queues quite so much. No-one could doubt that I'm British!
