I tell cold callers I'm very interested but a bit deaf, my hearing aid is not working properly and can they speak up. The idea is to deliberately miss-hear what they say, ask them to repeat, only louder, and see how loud I can get them to shout. After a while I say "I'm not really deaf" and was just wasting their time, as they were doing with me.

Sometimes I pick up the phone, listen to cold caller alias name, repeat it several times in an incredulous tone and then - bam! - pretend to recognise them. I ask them if they remember the hell of a time we had at the 1985 summer camp when we set fire to the wooden shed, and I keep making things up and go on and on until they end up terminating the call.

Try to sell cold callers something and be very insistent. Works well. Also good for door-to-door sales people, especially if they're wearing poor shoes.

They are a special breed-like normal accountants, but without the soppy sentimentality. These are the oncologists of market capitalism.

The uncomfortable truth is that we all enjoyed the party far too much to query where all the booze was coming from. Now we seem intent on lynching the barman for letting us get drunk and attacking the Government for letting us get a hangover.

Consumerism has become a new religion, complete with its high priests at Which? and its fatwas against anyone with the temerity to try to sell anything at more than cost price ... It is a depressingly medieval outlook on economic life.
