Nowadays you get challenged if you are leaving the council recycling centre with the container in which you brought your things there on foot.
Oh but to live in such a liberal paradise where you can bring things in on foot! Here in Birmingham they won't allow you in without a car. The 3 recycling centres for a city of 1 million souls have multiple hour long queues on Saturdays in the summer. We too can pay for it if we don't have a car. They wonder why there's a problem with people fly tipping..
