So the service was lousy, the wait staff were rude and on top of everything else, you got sick.
Well, it might not just be potential customers who get the memo. Turns out New York City's health department is also paying attention.
Health department officials discovered that people who posted complaints of stomach illness on Yelp almost never had bothered to call the city and report the illness. Trawling public social media sites may help keep track of restaurants with potential problems, they concluded.
"While investigating an outbreak of gastrointestinal disease associated with a restaurant, the New York City Department of Health and Mental Hygiene noted that patrons had reported illnesses on the business review website Yelp that had not been reported to DOHMH," Dr. Vasudha Reddy and colleagues reported in the Centers for Disease Control and Prevention's weekly report.
