Well the brother called me back a few moments ago and let me know the problem was a blown radiator hose.
After a few seconds into a tirade from him that I was trying to rip them off, I reminded him that I offered a diagnostic to determine the reason for the cars loss of coolant and overheating and that the 79.90 would be applied to the repair.
He was still ranting so I kinda lost my cool with this idiot and I said WAIT A MINUTE AND SHUT THE HELL UP
Do you remember the book COC and he said yes, I then said you are now guilty of apostasy as you saw the book and sought me out so stick that in your pipe and smoke it and don't come back and I hung up. and started cackling like a fool
