I work at a college and once a professor made me stand next to the copier while she was printing out her final exam because she was convinced that it only ever worked if I was in the room.
Definitely. That’s why I prefer the term “Fixed by Intimidation”
Some time ago, I had a microwave that broke, and I thought “I’m certainly not qualified to fix a microwave, nor should I even attempt it, but I’m curious to see if it’s something obvious”. So I took the cover off, peered inside for 5 seconds, thought better of touching anything, and replaced the cover in preparation for the landfill. Just for fun, I plugged it back in… and it worked perfectly for another 10 years.
