DD1 has just taken on the tenancy of a house, asking for it to be unfurnished. We found tables, chairs, wardrobes etc. smashed up and hidden behind and beside the garden shed! With permission we took many trips to the waste recycling centre. When one of the staff watched me empty a bag of broken hard plastic for landfill he spotted fragments of plasterboard mixed in, whereupon I was told I had contaminated the whole bin which would have to be removed and hand sorted! I had no idea I had broken the rules, and still don't know why. Unfortunately I had to visit a few more times and endure his evil stare!
