There is an escalator that is wide enough for two people, the people on the lefthand side are standing still, the people on the the righthand side are walking up.
It's peakhour at the the train station and there are a billionty people funnelling their way onto the escalator in two lines depending on wether they want to walk or stand.
Why on earth would you then step onto the righthand side (where people are walking) and stop??
Why aren't we allowed to carry tasers to deal swift justice to these annoying people??
