A Brooklyn barbershop customer’s face was sliced open after his stylist shoved him through a plate glass window Thursday afternoon, police said.

The bloody 3 p.m. scene at the Levels Barbershop on Nostrand Ave. in Crown Heights unfolded because the victim, 33, was unhappy about his haircut, witnesses said.

He threatened to withhold payment, enraging his barber, who allegedly shoved him through one of the store’s front windows. Source
