This doctor needs to work on her tableside manners.

The Staten Island physician went ballistic on a diner manager — flashing an apparent badge and threatening to deport him — after he asked the woman to leave so the eatery could close for the night, police said.

Dr. Nicole Borges was arrested on charges of criminal impersonation and criminal mischief for the incident at 12:50 a.m. yesterday at the Kings Arms Diner on Forest Avenue in West Brighton.

She was released without bail.

After Borges and a pal had finished their meal, the manager, Antonio Hernandez, told them that Kings Arms was not a 24-hour diner and that they had to leave.

Hernandez told cops Borges flashed what looked like a police badge at him, said she was a cop and threatened to use police powers to make his life hell, sources said.

“You don’t know who I am. I’m a detective,” she allegedly said, according to cops. “You don’t want to mess with me. I’m going to call immigration and get you deported.”

Her rage continued when she took a swing at Hernandez as she paid the bill, leaving a scratch on his cheek, he said. He claimed he had video images of Borges flashing the badge.

Her lawyer, Mario Gallucci, said yesterday that the workers at the diner are lying, and that Borges threatened to call the cops after they mistreated her.
