Same in France, every little town has it's own 'dechetterie, immaculately kept, every thing in it's place, the right place.
Ours is run by Patrice, his tip, his rules. If you can hold a conversation concerning the chances of France v's England in broken French, clean up the mess you made emptying your trailer, and help others unload theirs when it's busy you can have anything in the place, well anything he hasn't squirrelled way first.
If you want something in the metal skip he'll go in and get it for you, if it's not there you can place an order and he'll put it aside for you, pallets, 40 gallon barrels, etc. His theory is simply that if you can use it the 'Marie' - local council, doesn't have to pay to dispose of it, so everyone's taxes go a little further and you save a few euro's so you can buy him a small beer next time you are in the bar.
A lot of Brits here whinge about the French and their 'individual' attitude to the interpretation of the rules, and boy are there some rules here, but it does work both ways, well sometimes!
