Which unwritten British queue rule is the most sacred? Rank them from holy to heretical!

Skipping the queue is the fastest way to unite strangers in silent, seething rage. Even the politest pensioner becomes a vigilante.

Stand too close and you'll get the passive-aggressive shuffle forward. There's a phantom two-foot bubble and everyone knows it.

No shouting required — a single well-timed tut can shame a queue-jumper into oblivion. It's Britain's most powerful weapon.

Holding a space for three mates who are 'just parking' is grounds for excommunication. If they're not here, they're not in.

When it's finally your turn, the silent nod between queue-mates confirms the sacred order. Ignore it and you're basically a monster.
