A safety guard at a Taco Bell slapped a girl clear throughout the face as she tried to put an order … and it is all on video.

Footage from contained in the Taco Bell Cantina location in downtown Los Angeles reveals the restaurant’s safety guard confronting a girl and smacking her upside the top.

The video picks up with the girl beelining to order from a kiosk … and the guard is scorching on her heels. He grabs her arm, turns her in order that they’re head to head and unloads a vicious slap.

The lady walks away and the guard follows … she tells him to get away and he tells her to depart the premises.

Clients within the retailer largely watch in surprised silence … and the girl argues with the safety guard earlier than he is finally capable of usher her out the entrance door.

Unclear what sparked the confrontation … the video doesn’t present the buildup.
