I err on the side of "this is bullshit" but... have you met cats?
My cute little booger has gotten it down to a science that she can even get into my keyboard tray when I have my desk in standing mode. Leap up, grab on my belt, and leap into the tray so fast that I don't even realize why my hands feel fuzzy. And if I am sitting? That is easy mode.
Which leaves a little ball of fur with four paws, a nose, and a tail, finding ways to get the best possible shortcuts. And mashing even more as you gently try to pull her out and she has decided your enter key is the best thing to hold on to and rip off.
And if you work from home... or just around cats in general? You are either locking them out every time you do any work or you are just rolling with it.
Similarly, if they are using a fancy management interface (or are just sickos who are obsessed with emacs shortcuts): I have genuinely been shocked by how easy it was to update a config and reboot a server.
Like I said, I think this is a bullshit excuse. But, depending on setup, it is very possible. And is mostly solvable the same way you prevent your own fuck ups.
