Right. I remember a very small non-profit that was so happy with my code the owner wouldn't let me fix a bug (lack of a fail-safe), having convinced himself it would never be a problem the way the software would be used. Despite the fact I was working for free. Two years later, someone else was assigned to use the software, and that "bug" incurred a phone bill that killed the non-profit outright, as I had predicted could happen.
