I hate it when you're out in the rain and you get stuck behind someone with a Brolly (umbrella) and you can't overtake them without getting poked in the eye with them or if someone's approaching you with one, they don't see you till the last moment and you have to serve to miss them and usually it's either into a puddle or out onto the road.

I hate it when you're in the pub & someone comes upto you & asks 'Is someone sitting on that seat' and points to an empty seat.

I hate when you get on a busy bus and people all stand huddled at the front, instead of moving down.
