I get them too, accymel, selling double-glazing when any fool can see the whole house is already double-glazed. I also get "driveway specialists" offering to block-pave my fairly-newly-paved drive and fascia-board salesmen who I delight in telling all the houses in our road have aluminium boarding which will last longer than I will. The worst, though, are the ones with dusters, dish-cloths and such. They always tell me they're on a "scheme" to "help them back into work", having presumably just come out of clink or whatever. I tell them I can't afford to buy dusters and use old, torn-up underwear.
I'm considering putting a sign up in my porch like Frank Sinatra had on the gates of his house, under the bell-push. It said, simply, "You'd better have a damned good reason for ringing this bell".
