"It's not a threat. It's a way to get the service you deserve."

It was during a trip to France last year that he had the brainstorm for ReviewerCard. As Newman tells it, he was at a restaurant ordering breakfast and was treated rudely by the waiter when he asked for green tea with his meal instead of ordinary tea.

Newman expressed his displeasure. He told the waiter that he planned to post a negative review on TripAdvisor.

"The next thing I knew, the waiter was back with the manager, who apologized and offered to pay for my breakfast," Newman recalled.

Thus came his epiphany: "Why can't waiters, hotel workers, concierges know that people are reviewers? If that French waiter had known at the beginning that I write a lot of reviews, he'd have treated me like Brad Pitt."

To boost one's chances of Pittness, ReviewerCard charges $100 for a black card that says, "ReviewerCard: I write reviews." Flash your card, and the world's your oyster.
