Maybe it was Kafka who wrote a story about a man who was so disturbed about the passing of time that he took to waiting in queues so that time, and thus his life, would be spent more slowly. Anyway, they’ve done a study of attitudes to people jumping lines. Apparently:

When a person intruded into a line, this resulted in an objection 54% of the time. However, when 2 people intruded at once, there were objections 91.3%. The figure shows that 73.3% of objections came from people behind the intruder, and the person directly behind the point of intrusion objected most frequently.

I’m presuming that these were only vocal objections as I thought there would be more if it included unvoiced ones, but you’d have to read the actual study…
