Sudden rule change
The Officers' Club at Patrick AFB used to have a ban on flight suits; (the membership was 90% retirees, few of whom were pilots). One day, a new General took over the Eastern Test Range and promptly went flying with us. Afterward, he suggested adjourning to the Club to "debrief" and was discreetly informed of the policy. He said: "Oh, yeah? We'll see about that!"
