Honestly, it happens more than you'd expect. A good thermal camera is a perfect example. Found a failing motor bearing during a routine check last month, way before it seized. That one catch saved a client's whole production line from going down. The tool cost was covered right then and there by the service call alone. It's not just about fixing things, it's about seeing problems you didn't even know were there. That kind of foresight is what keeps people in business.

Oh man, I'm the worst at that stuff. I'll follow some pointless rule for years until someone points it out. Your nephew just saved you all a lot of future standing around, lol.

Totally get that, my friend once locked his keys in a running car.
