Strongly agree and want to pile on with some more very normal times to queue politely:

- waiting to get food at a quick service restaurant

- waiting to get into a show

- waiting for the bathroom in a public place

- merging while driving in traffic

Any time there is an uncoordinated mass of folks on a limited resource it helps simplify things all around for a FIFO process. The chaotic "sharpest elbows wins" approach being better is the exception not the rule.
