This is from my days as a mechanic at a beach area Chevy dealer.
I was checking a coolant leak on a mid-90's Chevy Suburban when I found the problem- the top radiator hose had sagged enough to allow the engine cooling fan to contact and cut it. This was a fairly common problem on this generation of Chevy / GMC full size truck equipped with the optional 7.4 liter / 454 cubic inch engine. This hose is over 2 feet long and bends at an extreme angle where it attaches to the radiator. A TSB ( technical service bulletin ) was issued. A special add-on bracket was made to support the hose in the middle where it sagged.
After replacing the hose I explained the problem to the service writer, and he let the customer know. I also noted on the repair order that without that bracket, this problem would most likely happen again. The customer acknowledged this, but declined the repair, saying she had other things to do and couldn't wait for the part to arrive from the warehouse. She never returned to have the work done.
A few months later it happened again. This time the engine lost all its coolant and stir-fried itself. When it was towed in, its service records were pulled. Everything was there. My ass was off the hook, but the dealership still agreed to pay half the cost of replacing the engine, despite the fact that it was the lady's declining the earlier repair that caused her engine to be ruined.
