Went to National Tyres in Guildford for a pair of tyres today (Avon on buy 1 get 1 free offer). The process was nothing special, the chap took the wheels off, took old tyres off, put new ones on, balanced, etc. Then he puts the wheels back on the car, tightens with impact wrench (again, nothing special) and then... takes a torque wrench and tightens the lug nuts to the correct torque !!! I couldn't believe any garage would do it these days for lug nuts !
When I asked the chap if this was their normal procedure, he said, yes, they normally set impact wrench to about 80Nm and then hand tighten them to 110Nm (or whatever the proper torque is)
P.S. I, however, had much worse experience with their other branch.
