Our green bin only gets collected every three weeks which isn't enough so ... I put that out twice ...

. I fill both the green bin and the brown bin (garden waste which we don't use as we have a gardener who removes waste)... and I live on a t-junction corner... so I put the green bin in front of my house and perch at the window waiting for it to be taken. The bin truck then turns left down a cul-de-sac and I sneak out, transfer the remaining bags from the brown bin into the now-empty green bin, and put it back out on the road to the side of the house. Meanwhile the truck goes down the cul-de-sac, turns at the bottom, and heads back up past my house the other way, re-emptying the green bin on the way past

. They either have never noticed that there's an "extra bin" without a corresponding house or perhaps just don't care

This is not what you meant but a story I thought I'd share

. Dinnae tell the coonsill.
