I had a mate who used to work for Comet, but he didn't work for them for long! They were always getting their sales assistants to push one thing or another and one month it was Beacon Gas (when the gas companies were deregulated/privatised whatever!) It's like he said, how could he sell someone gas if they'd only come in to buy a video? Don't exactly go hand in hand does it?
Another story, I went with one of my kids to buy a TV DVD package and the assistant was trying to push him into buying a posh Scart lead. A posh Scart lead for £74

Needless to say when he looked at me I shook my head. The assistant then remonstrated how good this lead was and how an 'ordinary lead' would spoil the picture. In the end I got a bit shirty and asked "What's so good about this flippin' lead then?", "It's got gold contacts" says the assistant. "Oh yes" says I "What's so good about that then?". "Gold's a good conductor of sound!" After laughing, I said "No, gold's a good conductor of electricty" which it is, hence why you get gold plated contacts in connectors etc. "Are you an engineer then?" says the assistant. "Yes, as a matter of fact I am!" said I. That took the wind out of her sails
Anyway, you had to be there!!!
