I'm on a few Veteran pages on FB. One of the recurring themes is the poor quality of chow in the DFACs. It's primarily Army but I have also eaten at the DFAC at DMAFB when we wintered there and saw some questionable quality in that place too.
IMO the largest reason that the chow halls can get away with lousy food (under / over cooked / contaminated) is due to the lack of senior NCO's and Officers eating there. If the Mess Sgt / Ofc knew that on any given day or meal they might have several field grades and E8's / E9's eating there, they would straighten the hell up damn fast. If I were the installation, Brigade, Division CO I would make it a mandatory OER bullet point that the Officers I rated or senior rated ate a minimum of 3 meals a week and not the same meals when in garrison. I'd also be eating there and if there was a problem with the food I'd be exercising my chain of command to rectify the situation. I see this as a poor leadership situation.
Unfortunately a lot of the DFACs in CONUS are civilian run. Also IMO that needs to change.
