There should be some sort of rule that people should not stand in front of the exit doors when they are not getting off at the next stop, unless there is no space to move further in.
People who don't move towards the rear of the bus when there is space make me angry.
People who like to stand in front of the exit doors but are not getting off at the next stop, and don't move towards the rear of the bus when there is space make me even angrier.
