Around 1993. An overseas government office, high ranking guy,light-years beyond my rank, brilliant in his political field, complains he's lost data, AGAIN, furiously summons me to make amends about the deplorable system of which I am in charge and FIX THIS SHIT. Office has a low standing safe next to his desk. Each safe has a little magnetic sign, one side says "open" the other "closed". While the safe was open, he put the sign on top of the safe, out of the way. It seems (who knew?) that placing your floppy disks on top of magnetic signs might corrupt your data. I accepted responsibility, I told him, because I didn't anticipate he might do this, and I should have briefed him. On one hand it was politically expedient to end the quarrel quickly. On the other, perhaps true: never assume your users or clients have a single shred of intelligence beyond their field.
