A group of friends walking in a horizontal line formation. One of these can easily cover the width of a hallway with very few people, and can cause extreme frustration to the masses when they move at a slow pace.
Sorry I am late, there was an anti-social line blocking the main hallway, then by the time I reached the exit I needed the toilet again.
