First thing they did, they tried to charge him for their time. These were busy people, after all. They ran the banks. They issued the credit cards -- millions and millions of credit cards. It wasn’t as if they could drop everything and come rushing to the White House just because the president decided he needed to see them right away.
So they charged him what their time was worth. (Their time was worth plenty, they all agreed.) Then they tacked on a little extra for the inconvenience. And a little extra on top of that, just because they could; they called it the Presidential Presumption Charge.
