It happened a long time ago, but it taught me that there's a very
large human element to computers.
I submitted a pile of coding sheets to keypunch and got the deck back
with the note: "I didn't know if you meant zero or "oh" when you
write (O with a stroke through it), so I punched some cards both
ways."
One worthless box (2000) of cards.
After that, I learned to drop by keypunch to occasionally chat with
the ladies (it was comprised entirely of women), and occasionally
drop off some munchies and other things. They knew me and I knew
them.
And I never had an issue with keypunch after that.
