I said, "Are you telling me you don't want to work on my car?"
Service guy, "Pretty much, sorry."
I had to go the GM of the dealership to get them to eat the $150 "diagnostic fee", since they hadn't diagnosed anything.
Luckily for you, there a lot of oilhead experts out there.
This isn't so bad really.
They should be ashamed for charging the $150 and even more for throwing in the towel but if you got your $150 back you're way ahead of most.
It's OK to refuse work, not so OK to charge for doing so.
