This guy had no tolerance.

A fight between two roommates that started over a pinched beer ended when the alleged brew thief stabbed his roommate and landlord in Northeast Philadelphia on Sunday night, police said.

David Gentner, 50, and his 33-year-old female roommate got into a heated argument about 8:30 p.m. at the house where they live, on Sanger Street near Summerdale Avenue, because Gentner took the woman's beer, police said.

At some point, the woman threw a punch at Gentner but missed and the 54-year-old landlord got between the two, according to police. Gentner then pushed the landlord out of the way and punched the woman in the nose, police said.

He then grabbed a knife and cut the woman on the back of her head and on her left bicep before stabbing his landlord once in the right arm, police said.

Cops were called, and Gentner was arrested at the scene. The victims were taken to Albert Einstein Medical Center, where they were treated for their injuries and released, police said.

Gentner was charged with two counts each of aggravated assault, recklessly endangering another person and related charges.
