Most kitchens receive very little baseline funding above and beyond what they take in as "revenue". It is actually the salaries of the employees (less military staff I believe), the cost of food, and all the other things directly related to providing that service (less utilities which are normally centrally funded on most bases). Everyone always compares the cost of rations to what it costs to buy the food to eat at home. If you calculate the food costs, the cost for dishes, the power to run your oven/microwave, coffee maker, refrigerator, and the value of your time to prepare the meals (and the portion of the initial outlay for the appliances over their life span) what does that equal? You really need to look at comparing the cost of rations, vs. the cost of eating at a restaurant at cost.
