Actually, no. Should take less than 5 min/wheel with a torque wrench. They are charging you a minimum 1 hour labor...
Go buy a torque wrench for about $50-60 and proper size socket and you will be able to do this yourself from then on.
You might consider a cordless impact wrench to help you on the road if you need to change a wheel/tire--I have had a Craftsman 19.2 volt cordless impact wrench for several years--it will torque to near specs and you finish off with the wrench.
Personally, after one re-torquing, I don't bother again unless I remove a wheel.
