Ever tried that at a busy park? I did something similar last summer when a car's headlights were messing up my shot of the milky way. I just walked over and said my camera was picking up their light, and could they maybe point the car the other way. They were super cool about it and actually turned the car off completely. That little chat saved my whole night of pictures. It really is amazing how often people will help if you just ask.

No kidding, learned that the hard way too. It feels silly torquing tiny bolts until you strip one or snap it off in a hole. That five seconds with a torque wrench saves hours of cussing and drilling. Your point about comeback jobs says it all, that's the real proof. Cheap insurance against your own future dumbass moment.
