Many sysadmins have to learn those things on the job, and as many are needed for "first impression" things when working with management - or management will just "roll on past not listening" - those skills and ability to recognize when something may be wrong despite it "working" - that would benefit everyone.
The "no" thing, that's for self-preservation, they need that skill if they're going to do any sort of sysadmin work.
Anyway: Bravo to the user. Consider talking to them more about their experiences (:
