I've just come across this story - a fantastic way to turn negatives into positives.
After being blackmailed into advertising by Yelp, the owner of a San Francisco Italian restaurant decided to embrace negative reviews. Owner David Cerretini actually encouraged his clientele to leave him 1-star reviews in exchange for 25% off any pizza. It's working rather well for the business, and the reviews are hilarious.
Botto Bistro, an Italian restaurant in San Francisco, is vying for the worst Yelp rating in the Bay Area by offering customers 25 percent off for their 1-star reviews. Owner David Cerretini, who tells SFGate that the promotion is "the best business move I have made in years," says the whole thing started when Yelp blackmailed him. Cerretini claims Yelp called him 20 times a week asking him to advertise. He did, to the tune of $270 for six months. But when he stopped advertising, he claims his reviews turned negative and one of his best reviews even vanished. That, according to Ninth Circuit Court of Appeals in San Francisco, is something Yelp is legally entitled to do. So, Cerretini hatched his 1-star plan.
