When you get home, loosen each nut one at a time and re-torque...
One at a time does not work if you three step your torque, as recommended in my owners manual. All have to be loose to start.
Agree about the tire shops. The manager/shop foreman may be as knowledgeable and experienced as they come, but he will not be the one in the back doing the work. It will most likely be some young fresh out of high school kid doing tire changes. He probably was trained the right way, but uses shortcuts and sloppy procedures when the boss is not looking.
I'm sorry but this is another jab at workers and it's getting pretty old to me. Is this the type of behavior that you do in the workplace, change your ethics, procedures, and work pace when not directly under supervision?
FWIW, I've worked in some shops where the employees were on a higher road and showed better customer appreciation than management. /rant
IMO, torquing lug nuts is not the exact science necessary for proper wheel installation that some profess. For steel wheels, there is quite a bit of latitude in the amount of torque applied. For aluminum wheels, as close as you an get is a good target. I know the tire shops use a gun setting and, depending on line pressure and quality of their tool, can vary a lot. They tend to over-torque because the alternative may be the loss of a wheel.
