What a wonderful thread. lizzypopbottle I too wonder what on earth people are doing at traffic lights when they change to green and no one moves! It also annoys me when people dither at roundabouts thus defeating the purpose of roundabouts - to keep traffic flowing!
And hairdressers who ask what product you use - and they don't mean shampoo.
And people whose knee jerk reaction is to counteract what you've just said: 'bit chilly this morning', 'oh it'll be 21C this afternoon' 'Lots of traffic about today', 'oh, I didn't have any problems'. 'The local shop is out of milk at the moment', 'oh I just drink mine black', etc, etc.!
