I used to work in defense. The latest secure phones would tell you who was calling and from what number. When someone I knew called, I'd pick up and answer with a gruff voice, "Pentagon." There would be dead silence while (I imagine) the caller looked at their phone to make sure they had called the right number.
At least I was amused.

If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
