I'm aware. There is also such a thing as "choosing one's battles", sure. You can't make a crusade of every little detail. But you must raise the issue.

Proposed way to do it: One argument I have used in the past on the job is that 0.5% here, 0.5% there, after 40 corners have been cut, does add up. It's enough to transform a project from "quick and dirty" to "customer support headache" and "bad press".
