By that, I mean what’s thing have you done that’s the most likely for someone to react with “how the heck could you have done that on accident?”
My example: I successfully cooked a prime rib on accident. I was in charge of the house while everyone else was gone, and there was a prime rib slow-cooking in the oven. The problem was that a mist was coming out of the vents, and I didn’t know it was normal. So I’d see the mist, turn off the oven, call my parents and grandfather, they would assure me it’s normal, I’d turn the oven back on, and the cycle would continue because I don’t risk that stuff. When they finally came home, we had the prime ribs for dinner, and the way I caused it to cook actually improved it. They bit out of it and immediately said “this is the best prime rib I’ve ever had”. Thus I accidentally cooked a good prime rib. That’s a positive experience anyways.
What some might say is my most profound negative example: There was a Minecraft level that was a replica of the whole nation of Denmark, and while the features that would allow it to otherwise be destroyed were disabled, I accidentally found the glitch that led to its demise and eventual conquest by America.
I used to work at a snack foods factory and was checking on some equipment (that actually wasn’t the equipment I was supposed to be checking–I got my lines mixed up). It was adjacent to a conveyor that had crumbs from a different product on it, which was supposed to be turned off since we weren’t producing it that day. Said crumbs were spilling into another conveyor below it* that was in use delivering a currently-running product. These two products had non-overlapping allergenic ingredients (soy-containing crumbs were spilling into a soy-free product).
I alerted management to get the batch scrapped since it was contaminated.
If I hadn’t mistakenly checked the wrong equipment, it’s unlikely anyone would have noticed and A LOT of contaminated product could have been shipped. All products from that factory are labeled “MAY contain X, Y, Z” so in theory nobody with a severe allergy to X/Y/Z should be eating anything from there anyway, but consumers make mistakes and even a non-severe dietary allergic reaction is an unfun time I wouldn’t wish on anyone.
*It didn’t just always spill into the conveyor below it, it was supposed to have a catch pan but someone had forgotten to replace the catch pan after cleaning it.
Seems like they didn’t clean up very well since there was product spilling 0.o
