A tipster forwards us a totally insane email sent to New York City's Elite Yelpers - the frequent reviewers Yelp invites to special, free events (all of whom, it should be noted, must be at least 21 years old). It seems a Yelp staffer witnessed "absolute, abject terror in the eyes of a waiter" at a recent event who was "traumatized by the rabid ferocity with which certain guests attacked his plate of hors d'oeuvres."
