WTF is this? Squadron barbeques are for socializing (appropriately) with the troops, dining ins/outs and hail and farewells are for Os only. The chiefs do their own social stuff, and I don't go drinking with the boys from the shop, although I have been known to buy 'em a round if we happen to cross paths out in town, especially while on det. It's an arrangement everyone can live with and nobody "feels bad" about.
This concept of Os getting crushed for not "including" the Es is completely foreign and incomprehensible to me. I must either conclude the fleet has gotten a lot worse in the past year or... Air Force.
