A shocking video has been released of a female diner unleashing an expletive-ridden rant at a couple kissing in a restaurant.

The video starts with the woman, wearing a red San Francisco sweater, arguing with a cashier about the couple at a restaurant in Santa Monica, California.

The boyfriend of the woman filming the video tells the angry woman to leave, to which she replies: 'Excuse me! This is a place where you eat, not where you make out. Go get a room!'

'You're a sl** - go make out outside. You're a prostitute - don't you have any manners? Why don't you leave b****!'

She adds: 'I can't wait to report you to the police.'

As the woman approaches the couple, her boyfriend says: 'Step the f*** back!'

The woman angrily shouts: 'You're f****** your girlfriend in a public restaurant acting like a prostitute.

'You're sexually harassing me - you and that sl**.'

She then turns to the cashier and says: 'I want my money back.'

Turning to the couple again, the woman says: 'Do you know how much I want to puke on both of you? You are the ugliest b**** I've ever seen - you look like a little boy.

As she begins to leave, she says to another man waiting by the door: 'I'm an American - I'm from California. Go back to whatever...'

As the man tries to make her leave, she says: 'Excuse me!' and hits him with a stack of papers.

She adds: 'Go back you retarded foreign assh***' before finally leaving the restaurant.

Describing the incident on Reddit, the video poster said: 'Last night my girlfriend of four years and I were waiting patiently for a lady to order her food at this restaurant in Santa Monica, and I had my arms around her from behind and maybe kissed her on the top of the head once or twice, but that was the extent of it.

'Out of nowhere, the lady looks at us and exclaims emphatically how inappropriate [our] PDA was and how uncomfortable it was making her.

'I thought she was joking because of how little we were actually making contact. I turned and kissed my girlfriend on the cheek and made a loud smack, and that’s where she really lost it.'
