I don't have a lot of spare time, but I set time aside on a Tuesday morning to go Alchie spotting in my immediate local vicinity when the bottle/can recycling tubs are outside peoples houses ready for collection. I've noticed different behaviours around this activity. Some people carefully put all the non alchoholic cans on top to hide the real stuff. Some put their newspaper recycling bag on top of the box, so neatly flattened and folded so as to cover the contents like a well spread duvet, and some too ashamed to leave theirs outside will wait for the van to arrive and run out with it appearing to have forgotten, but every week, come on.
