There's people like that all over the world.
We have one locally.
Some years back we needed work done on our daily driver.
So it went to him.
Our daughter's car was booked in the next day for some major suspension work, and knowing the parlous state of her finances I told him to add it to my account.
To say I was surprised when I got the account would be an understatement.
Bearing in mind he's a one-man-band, over five days he managed to wring a total of eighteen hours work out each day...ninety hours in all on the two cars.
We have never been back.

What does it profit a man if he gains the whole world and yet loses the value of his soul?
