It's a good story, and only a story. When I worked in a garage, women were the best customers because they didn't think they knew anything, and men were by far the worst because they thought they knew it all. Here's a couple...
After paying in the office, middle-aged guy comes back in all guns blazing, accusing us of wrecking his gear box as he can't get the car in gear. Muggins obliges by coming around to the car park. After yelling at me all the way, giving me a long list of things we'd done during the service to wreck his car, he jumps in to show me the problem. Punter leaves happy after I moved the seat forward for him so he is actually disengaging the clutch...
Mr. Know-it-all wants his plugs changed because he has a misfire. Customer is always right, so after grabbing plugs and spanner from the stores, proceed to remove plug leads. Punter goes into one saying that it must be done one at a time otherwise they won't go back in the right order. Next he tells me the plugs I've got are too hard, and then proceeds to tell me how they work. I proceed to remove all the leads and the distributor cap and put them on the bench, replace the plugs, put it all back together. Toss him the keys and charge him. Car starts and he drives off! (Sequel - it didn't cure the misfire that turned out to be a poor connection on the coil!!)
And so it goes on...
Next you'll be telling me someone came in for a new dipstick as the old one doesn't reach the oil!! First had my leg pulled on that one in 1973!!
