So the shop just rid itself of the toxic mechanic, but now it's left with all the poisoning he did to the new ones, new as in one just came from jiffy lube and the other came from a GM dealer a little over a year ago. The GM guy is can work through most issues but doesn't know things like running a cutting torch etc, the jiffy lube guy is useless and is too arrogant to learn anything so I'm not worried about him, if he comes around he comes around. But the GM guy I would like to help if I can, but he gets mad every time management wants a second opinion on major repairs. Any ideas?
