Societal pinch point

A societal pinch point is a situation, place or experience, created either by accident or without knowledge / inadvertently by the creator, that forces human interaction and will inevitably lead to one or more involved parties entering / leaving the situation angry, upset, hurt, anxious, depressed and may end in violence. Many people avoid these societal pinch-points all together out of anxiety or fear. Examples: - Merge lanes - Any place humans have to form more than one line - Any situation where manners / etiquette is unclear - Parking lots - Any physical place where people want something that there are too few of - Being the first car in front at a red light
