OK, so very worthwhile cause guy knocks on my door. He shows me a crate of tea towels, pens and dusters plus an id card. He proceeds to launch into long story of how he is just out of prison and if he can sell something he gets a %. I say "no thanks" to which his smile disappears and he asks why I let him go on? Eh?? I say "no thanks, never buy at the door" and close it and he says "scum" to the window. I then opened the door and said he needed to take the knocks with the job and don't call me scum and he slinked off. Is this a genuine venture? I think not. Should I have bought some of his old toot?
