In my world, everyone who takes skytrain in the morning would kindly move as far back from the main doors so that more people could get in board! Freaking almighty, Japan/Hong Kong would laugh at how much SPACE we leave!!!!!!!!!
In my world, people would step aside from the skytrain to let people out FIRST and then step in instead of BARGING their way through the door like a raging bull. Sometimes, I have to push people aside just to let me out! Oh, I'm going to freak one day.
