Yes, they do slimy stuff, but nothing like the parent was describing. I've never heard of a maintenance place taking apart your engine without asking you first.
That's exactly my point. Why aren't costs agreed upon first in healthcare? Sure the doctors, hospitals, insurance, etc will lose their ass on some jobs but it should more than balance out over time.
Oh sorry I misunderstood you, I thought you were referring to the car repair industry's upsells.
My own story is when I went to an ENT for something unrelated and he asked me if it was okay to pull out a hair he saw on my ear and I said yes, and then the bill had a $500 charge for it.
