Puzzle

I've never understood this: people who get to the top of an escalator and stop and stand and stare. Dead ahead, usually at a wall or a mannequin. Or blankly into space.

I could understand it if they stopped to look at a direction sign or similar, though I reserve my right to be irritated by them, but some idiot stood standing staring into space is not what you want to be stepping out to when it's your turn to get to the top of the escalator. There were six of us behind one such idiot this afternoon, all trying to look like we were just about to reach the top step.

In the end an old lady prodded his hamstring with her shopping trolley and we all sidled through the gap before he could reposition himself.
