A furious New York diner lost his cool grabbing a restaurant manager by the neck before slamming him against a bar and into an elderly woman - after waiting more than an hour for his omelette, according to witnesses. Nicholas Dematteis, 39, flew into the rage while at restaurant Bocca East during brunch on Saturday afternoon, and demanded a free meal around 4pm because of slow service, police said. Dematteis was arrested and charged with assault following the incident, according to the New York Daily News. Police said New York resident Nicholas Dematteis, 39, flew into the rage while at Bocca East (above) during brunch, and demanded a free meal around 4pm after waiting an hour and a half . 'We heard yelling and glass breaking, restaurant patron Jason Wirtz told the Daily News. 'The guy was screaming, ''I'm not paying for it!'' There was some expletives used in there.' The 34-year-old manager made attempts to calm Dematteis down, who waited an hour and a half for his omelette, when he spewed a homophobic slur at the man, according to another manager Joseph Verdi. He then allegedly grabbed the manager's neck and slammed him against the bar. Verdi added that Dematteis, who he said appeared to be drunk, was 'a lot' bigger than the manager. As the 34-year-old manager followed Dematteis outside of the restaurant, he grabbed his neck and hurled him into an elderly woman who was standing on the street, according to the Daily News. The woman got up after being knocked over and witnesses said she left before police arrived at the scene. 'There was a hustle and bustle out here and she hit the ground pretty hard,' said diner Julie Chappell, who was seated near the sidewalk. Authorities said Dematteis was previously arrested earlier this year in January for breaking into his girlfriend's apartment, according to the Daily News. Dematteis, an Upper East Side resident who lives near the restaurant, was arrested and charged following the incident on Saturday, police said.
