From my experience there’s some correlation between behaviors whilst getting on/off on subways, elevators and buses - when looking at different countries. It’s not 100% but I find those behaviors happen more frequently. For instance the pushing on/off buses, the subway and elevators happens a lot in China but all three are rare in the UK, but people in the UK *love * to queue; they really do. That way they know their entrance will be first come, first served rather than the person the most in a hurry/persistent getting through first.
(that’s socialism for ya!)
