One of the things that happens when a tire "tech" overtightens lug nuts is
that the brake rotors or drums can be warped by uneven torque. I use a torque
wrench on all of my vehicles now.

Got a 66 Mustang I bought in 87. Its got some really weird chrome rims--they
have slots instead of holes to fit different bolt circles. They use a
shouldered lug nut. You have to slowly tighten them up or you will cause the
shoulder to pinch. When I got the car we had to use a 3/4" air wrench to get
some of the lug nuts off.
Every tire tech I've ever watched just runs the bolt/nuts up with no regard
to what should be happening. I always run them up slow, sometime by hand.
Then I set my torque wrench about 15 lbs lower than what is called for. Once
I torque them at that setting I adjust for the final torque. I will confess
I only torque aluminum rims. Everything else I tighten by hand, unless we
are talking tractor tires, then I'll use the air wrench. Even then I
progressively tighten them. Might be a little overkill, but it works for me.

Something else I have noticed: tire shops are generally careful with torque
on lug nuts on cars. I can usually get them loose with no trouble. But if
they get their hands on your trailer/tractor or whatever they whip out the
impact wrench and just wail on them. Not sure why they aren't as careful.
You may have been the victim of a tire technician with more impact wrench
than brains. (-;
