Recently a customer about to collect his car after having it serviced, was found muttering about his wing mirror which kept moving on it’s pivot at speed. He claimed that it would not tighten up and was about to add more tape to that already wound around the pivot in an attempt to stop it moving. I said “Let’s remove the tape and I’ll see if I can tighten it up”. So he removed the tape and I got my screwdriver and tightened the pivot screw which went up from underneath. That made the pivot nice and stiff, so I said “Job done, put the tape away”, to which he replied “I didn’t know that screw was there!”
Well, you do now! I promised not to mention names if I ever spoke or wrote about it, so I wont…..
