Thank you for explaining. I wanted to know, but it wasn't my business to ask.
That's a good rule of thumb when you go inside, too.

For those who are curious, here is what was being served at the chow hall this weekend:
Friday dinner - 2 hot dogs, 2 slices white bread, Great Northern beans, carrots with peas, and unfrosted butter cake
Saturday lunch - breaded chicken patty, 2 slices white bread, gravy, navy beans, snickerdoodle cookie
Saturday dinner - spiral pasta, meat sauce, salad w/ French dressing, roll w/ butter, frosted chocolate cake
Sunday lunch - sloppy Joe, 2 slices white bread, peas, sliced potatoes, some undertermined kind of cookie (?)
For diabetics, you had the option to get unsweetened applesauce instead of the cake/cookie.
