Yep this happened
Same sort things happened to a friend of mine working at a computer dealer in London. He had the note stapled to a floppy, the photocopy of a floppy AND the floppy folded in half and stuffed in an envelope.
In a similar vein of totally not comprehending the point of technology, I knew someone who would format all his floppies, restore the (DOS) system back to “factory settings” and erase all files on the hard disk. Every single night. So that the next day it was like new. He didn’t even realise that he could keep stuff he’d been working on (like Wordstar Documents), because he wiped absolutely everything and because he had never done this in the past (pre-computer), he never realised a need for it after starting to use a computer.
