If you don't know the answer then you might as well give up ! Still, it's given us all a laugh. On this odd occasion, Kwik Fit was correct. Did you get a receipt from the garage that did the puncture repair as you might need it for a legal claim against them in the future.

I have always re-torqued wheel fastenings every time someone else has removed/replaced a wheel on one of my own vehicles. I have done this for more than 30 years; I have never, ever experienced one becoming less tight. Of course, I would never re-mount a wheel on a dirty joint face... Chris -- Remove prejudice to reply.
