Huh! If you are a food blogger and someone invited you to their restaurant to enjoy a meal and give a review, of cos you might expect it to be free.
But in his case, is he 'self-announce' that he is going there and expect them to give him free of charge meal? Who does he think he is? If he's really some big shot, they would have invited him there, not wait for him to annouce that he wants a free meal!
