"Chipotle announced its first loss as a public company Tuesday. But two weeks earlier, an unlikely source —the social media app Foursquare — had beat Chipotle to the punch, predicting in a blog post that the burrito maker’s sales would drop nearly 30 percent. Chipotle made it official Tuesday afternoon — reporting a drop of 29.7 percent.
