Like when they tick the service sheet, to say they have checked the condition and pressures of the spare wheel, when the car has an inflation kit !.
This happened to a friend of mine when he asked the service manager why this box had been ticked on his car ?.
He told my friend, that if it had been ticked, it had been done !.
Then marched him out to the car and lifted the boot carpet.
"Oh ...... It must be under neath the car then".
Got down on his knees to check in his nice suit, in an attempt to prove my friend incorrect.
Then took off at speed towards the workshop.
Somebody was in for hard time, that's for sure.
There is somebody who knows his products alright ( NOT ).
