Self-confidence is essential for any successful small business owner. Craig and Anne Stoll, of Pizzeria Delfina in San Francisco, seem to have it in spades. Their servers wear defiant t-shirts adorned with some of the restaurant’s negative, one-star online reviews. Like: “This place sucks.” and “The pizza was soooo greasy. I am assuming this was in part due to the pig fat.” Each criticism is followed by the eatery’s name & the phrase “People love us.” Of course, to be this bold, it helps if you’ve been named one of the country’s top pizzerias.
