Better than the bungling buffoons I took my last car to for a new exhaust.
They are a National company too.
The mechanic (I say mechanic - no qualifications I was told later) had to use the acetylene torch to remove some nuts and bolts (that's quite normal)
While he was holding the burning torch to inspect whether he had got the bolts off, I saw him accidentally run the torch across the back tyre. There was a huge cloud of smoke from the burning rubber.
He replaced the exhaust and did or said nothing about the burned tyre.
even though he knew he had done it.
He then gave me the keys and said 'there ya go mate'
I said what about the burnt tyre - he of course pretended to look puzzled.
When I got down to look I was really shocked. It was a wonder the tyre hadn't exploded. There was a foot long score mark right down to the last layer. He thought I wouldn't see it as it was on the inside.
He was going to let me drive away with it like that!
The manager was very nice and also very afraid that this would go further. As compensation they put four new top of the range tyres on my car and that was the end of it.
But I did shudder occasionally as I do a lot of motorway driving. 'If I hadn't seen him do it.
