Safety Meeting

We've exhausted our gallery slash bookstore slash snooty chachky store options, it's raining sideways and we find ourselves bellying up to the bar at Grumpy's ordering a couple of schooners. Just as we're settling in to watch the BSU/Ducks game, the guy next to me yells "Safety Meeting" and everyone runs outside....including a few tourists. How safe can it be when it has so obviously become part of the everyday lexicon?
