Coming from any other POTUS

I might dismiss this stunt:

Four of the most powerful business leaders in America arrived at the White House one day last month for lunch with President Barack Obama, sitting down in his private dining room just steps from the Oval Office.

But even for powerful CEOs, there’s no such thing as a free lunch: White House staffers collected credit card numbers for each executive and carefully billed them for the cost of the meal with the president.

Any other President and I may have called it just a lapse in etiquette but coming from Obama, I have to believe it's a very calculated and snarky move aimed to demonstrate his no-nonsense approach to big business. I hasten to add other qualifiers to "no-nonsense" like "disdainful" and "proletarian internationalist".
