My bins are new blow to world peace

I started with the odd beer can or cigarette packet dropped into the lidded bin meant for black-sack-only rubbish.

Luckily, I spotted and removed the offending items ahead of bin collection day, managed to fish them out and relocated them to the red and blue-lidded containers designated for glass, tin and plastic and paper and card respectively. No bother.

But the problem escalated. I'd nip out to deposit a knotted black sack only to find the relevant wheelie bin already rattling with bottles and cans (not mine) and in the wrong container. No way could I lean in to retrieve them without falling in.
