I'm a wee bit bin-obsessed, but only about my own bins.
I live in a tenement, and there are 3 tenement buildings all sharing a back court, where the bins are stored.
I've had to put a padlock on my general waste bin, because certain neighbours were constantly filling my bin up with their rubbish, leaving no room for my own! Apparently someone has taken issue to me padlocking my bin, as i regularly find it tipped over, or moved to somewhere i would never have put it, including one time finding it out in the middle of the road, where cars were having to dodge it.
WTF is wrong with people?
My blue bin, i have to check a couple of times a week to make sure no one else is using it...this one doesn't have a hole to fit a padlock through. For the blue bin, i don't mind if anyone else uses it, because i don't have enough of that sort of waste to fill it regularly. So if someone else needs to put their cardboard or cans or newspapers in, I don't mind. It's when the scum start filling it up with soiled nappies and other smelly, non-recyclable waste, just because their green bin is full... that's when i start going tonto, and will go out there with gloves and pull their crap out of my bin, because the clenny won't collect it if its got the wrong stuff in it.
It actually stresses me out. I think about it far too often!
