An off-duty NYPD officer went berserk in a Godiva store when she was told they were closing — even fighting police who responded to the call, cops said. Officer Amanda Villafane went to the store at the Stamford Town Center with her mother and Christopher Salvadore, 32, around 6 p.m. Sunday, police said. “They were told the store was closing,” Stamford Police Sgt. Brian Butler said. “They were not happy with that answer.”
