A man walked into a hotel. "I'd like a room for tonight," he told the clerk.
"I'm sorry, sir, but we have no vacant rooms," the clerk answered.
"Not even one room?" the man asked.
"No, sir, we're full tonight," said the clerk.
The man thought for a moment. "Please tell me, if the President of the United States came in and asked for a room, would you give him one?"
"If the President of the United States asked for a room, I would find one for him!" the clerk replied.
"Well, the President is not coming here tonight. So give me the room you'd give him!"
