People who exit the train and stand in front of the door deciding which way to turn.
Not only should they have already figured it out beforehand; the least they could of done was move further into the middle of the platform instead of blocking the exit way.
There are signs all around the subway station imploring passengers to “keep a look out” and “be aware of your surroundings”. Yet, there are still a stubborn few who believe the world revolves around them.
This problem isn’t localized to just the subway. This phenomenon occurs at department stores, elevators, escalators, restrooms, airports, etc. Wherever there is a chance to annoy others, these people will be there.
