A few years back a tyre place I used wrecked my locking nut key by tightening up the locking nuts with the air wratchet.
Today I went back to the same place as it is now under different ownership/management. Wish I hadn't
They started to remove the first wheel and I could hear the air ratchet being worked more than I expected it to be. So went out to take peek, and yes you've guessed it! they'd wrecked the key and bolt. That one had to be thrashed undone by hamering a socket over it.
I got the others by gently easing them undone with the knackered key.
There explaination was that the nut was "too tight".
End result, I leave with new tyres and nearly £150 lighter and only 4 bolts on each wheel as opposed to 5.
Went straight to halfords and got another set for £29.99.
Very irritated, but hey theres another lesson learn't. Go somewhere else or take the wheels off at home and pop them down in the other car.
Bloody garages!!!
