I usually try to be polite,knowing that it is some poor bastard who is
just trying to make a living, but when I got a call from B T at five thirtyfive pm on a Saturday with a B T Business Line offer , I must admit I was a bit rude.After all I am NOT nor ever have been a B T business subscriber on my home phone. Another nasty trick is the - Just a minute I will get him for you- then go and put the kettle on to make a cup of coffee.
