So you use a public toilet. And, being a clean sort of a person, you wash your hands. You then leave. But the doors of publlic toilets always open inwards. If they opened outwards, you could just shoulder them open, but no: the only way out is to use your freshly cleaned hand to grasp and pull the door-handle — a handle that, you just know, was recently grasped by some dirty bastard whose hands haven't been washed in a hundred years, and who probably works on a pig farm. Or in insurance.
I can't be the only person bothered by this.
