I recall getting a job back from keypunch with a note attached: "I
wasn't sure if you meant zero or oh (I always slashed my zeroes; the
keypunch form specifically called that out), so I did some of both".

Card deck into trash; go find a keypunch and do the stuff myself.

Management had this diktat that programmers were permitted to punch only
a few cards at a time; the time to punch a full deck cost the company
too much and so should be sent to keypunch.   Obviously, management
never had to work with the output of the keypunch pool...
