Those guys are like some of the local idiots that will put 600-800n ft/lbs of torque on the lug nuts. The 850 spec is 81 ft lbs.
They need to use a torque limiter on their air gun, I use the 80 lb one that comes with the Harbor Freight kit.
Lucky that you didn't have a flat in some remote area and have no chance of getting the lug nuts off. The remedy is to take a husky 1/2" breaker bar or
bigger with an impact socket and maybe a 2' pipe on it for more leverage.
It either comes out OK or it snaps off, (then you need to replace the stud).
I like to use a good coating of never-seez on the studs, it helps them come apart
later. Avoid that tire place after they repair the damage. They are Bozo's.
