Well, I apologise if it is meant to be taken as a joke, but I agree with the sentiment that other people acting in an unpleasant manner is no reason to drop our own level. Because if everyone follows suit, it would be a race to the bottom, and that can get very ugly in a big city. There are many perks to cities, but it comes with the down side of having to deal with crowds (made worse by our dated infrastructure), but that makes it all the more important to follow common courtesy, as opposed to treating everyone else as obstacles. Trying to be efficient with our commute is a good thing. But as is working together, as opposed to against one another.
