I don't see what the OP objects to about the way he was informed of the one guest policy. The dragon looked at the group attempting to enter and immediately pointed out the issue politely and offered him the paid access alternative. It's shorter than the version of the conversation he would have preferred but if I were waiting in line to enter the lounge behind him, I would early that shorter is better. The dragon did what was right according to the rules and did it politely. If the admission fee kept one kid out of that lounge, it is a good thing.
