> say "move, sloth" when people stand on the left side of an escalator That's insulting everywhere. Even if there was consensus about escalator etiquette (in Europe and America), that's still needlessly offensive. People too often assume how other people need to behave and then freak out when they don't. Apparently, japanese can assume such behaviour, at least on the escalator. Still, throughput is higher when you have two lines standing on an escalator, instead of leaving one line open for rushers. Though throughput would be even higher, if everyone stampeded up the escalator on both lines. So how SHOULD everybody behave?
