Sitting at the bar in my local pub I met a succession of different people as they came up to order a drink. The first was a carpenter, so I asked him which chisels he uses. Next there was a plumber, so I asked what make of wrench he uses. A model was next, so I asked her what brand of lipstick she uses. Then there was an electrician, so I asked which wire strippers he uses. He was followed by an accountant, so I asked what type of calculator he uses. Can you see a pattern forming here? Lastly there was a photographer, so of course I asked him what he drinks; lager or bitter?
