@yamapikariya I feel like there's a distinction to be made between Americans _visiting _a city and the people that live there.
For instance, when I lived in the SF Bay Area, ques for services locals used were efficient and well-ordered unless jackass tourists were involved. IIRC (it's been a while), everyone standing on the BART escalators would be on the left, leaving the right half of the escalator for people in a hurry to walk up or down the stairs. But mix in a few American tourists and it was just willy nilly people everywhere.
7:00 AM? All locals, everything is good. 1:00 PM? Good fucking luck.
Tourists also don't seem to understand or CARE that the city they're visiting has to run somehow, and they meander around on the sidewalks oblivious to everyone else like they're in a theme park.
TL;DR - - Americans know how to queue, they just don't do very well when they're out of their element in unfamiliar places.
