Nothing was going to get between a Long Island woman and her “all-you-can-eat” doggie bag.

A Long Island woman threatened to stab a TGI Fridays employee who tried to stop her from heading home with an extra helping from their “all-you-can-eat” deal at the chain restaurant, police said.

The suspect, 32-year-old Skylar Williams, allegedly walked behind the bar of the restaurant on Sunrise Highway and tried to pack up food from the promotion at about 12:30 a.m. on Thursday, police said.NYPD

An employee told her she wasn’t allowed to be behind the bar — and Williams allegedly flipped out, grabbing a bottle of liquor and swinging it at the man, authorities said.

Williams and a friend then tried to leave with the bottle of liquor, but the same employee tried to stop her, cops said.

She then produced a black knife and threatened to stab him with it, police said.

Cops responded shortly after and tracked Williams down to a nearby yard.
