Yeah, this reminds me of when someone ran into my son’s car and we were repairing the damage…and he tried to use a brad point bit to drill out a spot weld. A 1/8th inch drill bit is trivial in cost, though. Nobody uses my tools without asking, and if they don’t know how to use them, I’ll probably do it for them instead of letting them damage them. In my world, people who use my tools for free should pay for the damage, given that they paid nothing for the tool but possibly a smile or a “thank you” for the use. It reminds me of the time when I was out of town (in the US Navy), and my car was parked in my parent’s driveway while I was gone. One of my brothers-in-law convinced my parents that the car needed to be driven instead of sitting for months…at least he didn’t wreck it or blow it up, but I didn’t appreciate the “favor” when I found out about it.
