But they forgot that stewards also run the entire NPF operation in operational areas.
For the record, stewards don't make beds anymore and working the Wardroom is a only a small part of their overall duties.
About 15+ years ago, the Army eliminated all steward positions and decided it would run its messes with NPF employees (who tended to be inner circle friends of those in appropriate postions, but that's another story). Not six months after the last Steward had been posted out of the Army, the Army sent out a critical manning message for - get this - a Steward, to run a field canteen on an operation. Lo and behold, there were none to be had as the neither the Navy nor the Air Force had any to spare. The position was filled by someone else. Several months later the NPF Board of Directors was faced by a request from that same operation (and the Army) to write-off $50K-$60K (or thereabout) of spoiled and lost canteen stock because the non-stewards in charge of the canteen didn't know what they were doing.
Anything worth doing is worth doing well. Professionalism and training go a long way to ensuring this. Stewards are professionals trained in NPF management (their primary responsibility). Assuming that just anybody can do it can be a recipe for disaster.
