There is - at least - one in every "family", as you say. Making sure that "the people" has heard "His Masters Voice" at the end of the day.
To controller colleagues: Try to fly as much as possible (in the cockpit!) Wonderful eyeopener to see it from the other side
There is a safety aspect also. Lost VFR? Do you call the Olympian gods in xx ATC? No, I'll sort this out by myself - maybe.
Try it with a smile
Best regards
