Public transport is an essential service for literally billions of people, but not everybody feels like they have to act with gratitude about this. We only have to experience the school bus or the subway to see some sights that probably shouldn't be seen by anyone.
In particular, bus drivers can have it hard when it comes to dealing with the general public. Unlike train drivers, they have no choice but to have face-to-face interaction with every single one of their passengers.
This can become problematic when the people they are trying to get from A to B are uncooperative and even abusive, as one driver recalled when posting to Reddit. Explaining how a passenger had become belligerent after he wrongly claimed that he had missed a stop, the Redditor revealed how he had got his revenge without having to bend the rules. Needless to say, everyone else was on his side.
