Had to take my car to the mechanic today. I think I figured out how they charge you. Stage 1, when you first ask them how much it will cost to fix the car, they will give you a rough estimate. Stage 2, they will then tell you that there is a possibility that its gonna cost more then he had first predicted to fix the car. Stage 3, you start to worry that the price to fix the car is going to be too high. You start wishing that your car isn't too fucked and that hopefully you will end up paying the original low price the mechanic estimated. Stage 4, after making you think you would pay more then he had predicted, the mechanic will hit back telling you that you were lucky and it actually ended up costing just as he had originally predicted. Stage 5, you pay the guy what he asked for without negotiating because you are glad it didn't turn out to be the more expensive price he made you think you might have to pay. Thats how mechanics charge you.
