I always hear stories about the AF chow halls trying to keep other services out of them during the GWOT. I'm always glad I never saw it at the bases I deployed to. AF chow halls are superior, and by comparison by the Army & Marines treat their people like crap.
At Sather we'd get a good mix of new arrivals and guys you could tell who'd been at FOB Shithole for 6 months and had completely forgotten what hot food and normal showers felt like amid endless patrolling, firefights, and ducking rocket/mortar strikes. When those folks rolled in, usually because they were going on mid-tour leave or rotating out, they'd occasionally stop by our chow hall.
I never saw someone give them trouble, our services folks were great and our Squadron wouldn't have stood for it - we knew what the Army in particular was going through in Baghdad at the time. It's hard to describe the looks on some of their faces when they were eating real food, drinking a soda, or getting their favorite piece of junk food. It always made me smile.
I recall at Arifjan the smell of weed smoke, girl "soldiers" walking around in daisy dukes, and how they seemed all to be on a beach vacation. It was mind-blowing, and simultaneously brought on feelings of euphoria and jealous rage.
We were sunbrunt and dressed in bleached rags. When one of us entered an Air Force dining facility he was promptly told to leave, as it was for USAF personnel only. A gang of us returned (including my 2nd Lieutenant tank commander!) and we bum-rushed their buffet, loading up on moon pies and plastic plates of hot food. There was an Air Force master sergeant (a cook of some kind?) who threw his hands up in disgust once he realized our LT was leading the "raid."
