My favorite was the Costco guy who I asked to use a torque wrench a while back. He used the impact gun first, then went around with the torque wrench but they all instantly went "click-click-click" without moving, and he was happy. I pointed out that the only thing he measured is that the lugs are AT LEAST the recommended torque setting, but possibly much much higher, and that's not how you use a torque wrench. He just said that's normal procedure and walked away dismissively. Sure enough, I couldn't get them off the truck myself even using a long breaker bar as they were probably 200ftlbs and had to get help.Exactly why I do ALL my own maintenance.
