What about this scenario?
Its just hit 4pm on a fri arvo and everyone cracks open the beers as a lot of the smaller schools and clubs do. A few pilots (students, instructors) are sitting around sharing a few stories as they do every fri. arvo when in walk the Narc's asking for a random breath test. Whats the definition of knocking off? This is a real scenario where I worked and I know it is at a lot of the other smaller schools too. Is it now illegal to have a few beers on a friday afternoon on the premises?
