Some people were born for sales

The negative sell is always good: One weekend years ago, I got fed up with my daughter hogging the video for cartoons, and went out to buy the cheapest possible video, entirely for that purpose.

When I got to the till, the salesmen didn't know I followed him and came out with: "I don't know what sort of arsehole buys this f****** crap, I make f****** peanuts in commission". Unfortunately his manager also overheard it and placated me with a free service contract, presumably on the basis that the crap I was buying would probably let me down.

The video still gave good service, without a single repair until 2 weeks ago, 16 years later!
