Brits are renowned for being great at queueing, and you should never jump the queue in the UK.
Queuing is not a particularly British thing, but Britons are very well organised when it comes to it and they are really fascinated about it. According to the polls, they spend almost six months of their lives queuing. While another poll says that queue-jumping is the most likely rage-inducing things for Britons. We would advice you (out of personal experience) - never try to do that in the UK.
