Like Jack Reacher, "details matter".
Exactly! Although a bit silly, I quite like the show.
I had a PC problem about a year ago and the people couldn't fix it. I ended up working it out for myself and called them to let them know what the issue was. They were happy to get the feedback for it, not because of their failure, but now they know what to look for next time.
I am a bit the same as you in I like to know, even if I am not going to fix it next time. It is part of the story, and something to put in the bank to recall later, if needed.
Yes, yes, and yes. When I am tired of gathering knowledge, you may as well just light the furnace.
