In high school, my physics teacher was a man who had been born in Germany but emigrated to Canada as a young boy shortly after the end of WWII. One of the things he told us about the difficulty of adapting to his new country was the experience of people queuing for things like a bus. He said he was used to people in Germany rushing to get on first, often at the expense of those not as agile or strong as others.
He quickly came to the realization though that the orderly queues resulted in the bus loading quicker and more efficiently, with the additional benefit of much less stress and fewer injuries for the riders.
Historically, many Canadians share in the tendency to queue.

That tendency - to be polite and cooperative in groups - was one I used to benefit from when I worked as a wedding photographer.
