Should the bin get knocked over, escape whilst being moved from recepticle to transport, fly away in the wind at the recycling plant/tip etc, you would still be fingered for it.
Well, yes, but it would still be MY rubbish. As it'd only be a proportionate fine and an extremely rare occurrance, I think I could live with it. The window of opportunity for a bin incident is small, if we round up to 1% of disposals result in a bin problem, I'd have to eat drive thru McDs on average twice a week to get fined once per year.
