there was feature about this on a TV show here in the states. I know that jumping queues is just not done,and it is considered to be extremely rude. in the US,we are not very good or keen at doing so. just wondering if travelers to London observe the queue etiquette when there and not at home. also,do Londoners,when they are in the US,still queue,or "when in Rome"? I find myself getting in the queue when I am there. the only place we have a line is at the BART* stations in San francisco,only because the platforms aren't big enough to spread out.
*underground for those who don't know what that is.
