I'm in the Air Force and they provide us at no cost three meals a day.
For lunch and breakfast you have a cold option and a hot option. (Cold option is lunch meat, or cereal most days).
For dinner you get a choice of two meats and sometimes there will be several vegetables that you get to choose from and sometimes you're stuck with what they have.
It doesn't happen a lot but sometimes, I won't like either of the options and then I go out to eat. Or sometimes I'l have something to do and go out to eat.
But I always feel a little guilty paying for a meal when there's a free one for me.
