When I was in the Army Guard, as a Captain, someone decided to send me and another Captain to San Diego for some conference. I called the Navy base and made the room reservations. The civilian asked Captain, I said yes, two of us. We got there and there was a car, not a shuttle to pick us up. We weren't in uniform and the driver kind of looked at us. We got to billeting and they threw a hissy. We were from Kansas, had no idea about Navy rank and what their Captain was. They were full, so we did get a very nice room. We laughed about that for a long time.
