My dad got a big sideboard / display thing from the BHF a couple of years before he died. When I was clearing the house I contacted them and asked if they would take it back and could sell it on again, along with a few other things.
They sent round a couple of torn faced c*nts in a van a week or so later, who went round it, kicking the proverbial tyres, umming and awwing and giving it "see, what it is mate, is we don't normally take stuff this size" to which I replied that my dad had got it from the same place a couple of years earlier. You would have thought I was asking the pair of p***ks to buy the fucking thing. I was getting a van in myself the following week to dump the remains of whatev was left, so I could have just binned the thing myself.
I eventually got fed up and said that they could either take it or f**k off. They grudgingly took it.
