Yes, Prime Minister1986

Jim Hacker:
People can wait in the lobby. Or in the state rooms.

Sir Humphrey Appleby:
Some people. But some people must wait where other people cannot see the people who are waiting. And people who arrive before other people must wait where they cannot see the people who arrive after them being admitted before them. And people who come in from outside must wait where they cannot see the people from inside coming in to tell you what the people from outside have come to see you about. And people who arrive when you are with people they are not supposed to know you have seen must wait somewhere until the people who are not supposed to have seen you have seen you.
