Basically, this is a PEOPLE WHO thread about things that people do while walking that annoy you:
- stop dead in the middle of the pavement (interrupting flow / speed / orientation)
- walk slowly in the middle of a narrow passage (obstructing overtake)
- meander slowly from side to side (obstructing overtake)
- stop to look about in a really crowded / fast moving area (producing narrow channels of passage)
This is pretty London-centric I think. Never felt aggravated by this kind of thing any where else in the world.
