Idols & Randall

The other day during the Idols show, one candidate was refused a chance to even begin to sing and was rudely told by Randall "Go home, I will save you and your parent's money"

In discussion at the office it was pointed out that surely he is paid by the sponsor to listen to the wannabes and THEN be rude.
What would his reaction have been if the person had walked up to the judges and said "You are paid to listen to me so I will sing"
He seems to believe that he is more important than the sponsors who actually fund the show. Is this good for the brand ???
