Careful, you might offend some Jews with that one.

Fife is correct. Anyone with experience working in a shop knows, if you are not working on a car, you're not billing them for that time. If you leave it on the lift while waiting for a part, then that is the shop and mechanic's fault for not finding something else to do with their time while waiting. If they had nothing else to do while waiting, then their time obviously wasn't really worth anything because there was no other work to get done. $200 to remove a bolt is ridiculous.

That aside, I've fixed multiple fuckups from the Brauning automotive (not motorsports) company as well. Including one fuckup that cost the customer $1500 (incorrectly installed timing belt failed immediately after install due to installer error and it was denied and blamed on the car owner)
