Re: And it's even worse today...
A blank tape or disc would have been noticed by my customers in just a few hours. So, when you didn't have anything to ship, the process was this: Start writing something that looked like the correct install files to media, open media door part way through (we're talking about the 5 1/4" floppy and QIC-150 era here) to generate an IO error. Put broken media in an inappropriate mailing package. Dance on the package so there is an obvious footprint and other plausible wear and tear marks on the outside. Send package. Act surprised, and blame The Post Office, when media is not readable by the customer. Before the advent of downloads over a "network", that would buy you a couple of days development time. Who said we weren't agile back then?
