I would rather deal with that as long as they remember to put plastic covers over the seat before they drive it out of the shop in their greasy, grimy overalls
What annoyed me with my "car shop" were positions on the bill that they charge for without doing anything. Granted it's only a few bucks but generally a sign for bad business. Makes you wonder where else you've been ripped off.
Example: I made sure I filled the Window washer yet they tried to charge me for washer fluid.
or instead of changing the (marked) oil filter they just wiped it clean.
Needless to say they've never seen me again.
