The truth is I'd bet we get it wrong way more than we admit, so the "dumbest thing" isn't as rare as it sounds. I've done the exact same thing, stood there with a dead spider web on a sensor and ordered a $60 logic board in my head before touching the actual lens. A real fix for a garage door is usually the boring stuff, like wiping a lens or tightening a track bolt that rattled loose. My own opener just quit last month and the whole problem was a loose wire nut on the wall button, but before that I had a new motor picked out online. Most of these breakdowns are stuff that needs a rag or a screwdriver, not a truck full of parts.

Had a drunk guy huck a menu at my head one time over a wrong order and I just remade his food and ate the cost. Boss told me later I could have made him pay, but you know what? He was gone in 5 minutes and I got to finish my shift without dealing with cops or a report. The paperwork alone takes an hour and nobody pays you for that. My advice is just cover the food, keep your tips, and let it go. Some battles just aren't worth your time or your apron.
