The nightmare of the automotive trade, we are not all cowboys/joyriders/robbers unless you read the internet.
I’m an mot tester, I apply the rules to keep you and other motorists in a vehicle that is safe to use, I’m not interested in driving it for fun, I would like most people on a sunny day rather be out on my bike, not in my overalls spoiling your days. If I fail your car it isn’t because I’m a nazi with a clipboard, it’s because it doesn’t meet the minimum standard of roadworthiness, yes you washed it, but it doesn’t magic the broken spring back together or make the inner edge of your tyres grow back so there is no longer cords exposed.
