One of the clearest social rules in England is queuing (east cost translation: standing on line, west coast: standing in line). People want to know the bounds of the queue (where it begins, where it ends, single file or two-by-two, etc.) and they get very anxious when there are disruptions to the queue.
Today I was waiting for a bus, standing in a single file line about 15 people back from the head of the queue. The bus overshot the front of the line and its doors opened right in front of me. It was empty and the 25ish people waiting were going to have no trouble getting on. Despite my proximity to the open doors, I waited. Sure enough, the front of the queue snaked back in near perfect choreography and we all entered as preordained by the cosmic adjudication of the queue.
