A customer was targeted with a warning sign by a McDonald's worker before a vicious fight broke out.
The worker emerged from behind the restaurant counter and picked up a yellow 'wet floor' cone and started swinging at two female customers.
The two women scream at her “are you coming outside? You dumb b****” before a vicious fight broke out.
The fast-food worker was held down by hair by one attacker, while another woman launches a series of kicks at her legs.
A customer tried to hold back a second woman who is shouting “what the f***” are you doing.”
Horrified customers witnessed the fracas at McDonald's in Highbury, north London on Saturday evening.
The incident snowballed when other customers got involved and attempted to take the woman away from the McDonald's worker after pulling her hair.
The furious woman can be heard shouting “You stupid b****, don’t ever push me. Do you know who I am.
“Who the f*** are you pushing, do you know who the f*** are you pushing.”
The footage shows the employee being freed by customers who witnessed the fight while victim shouts “she’s trying to f***ing kill me.”
A spokesperson for McDonald's said: “ The safety and security of our people and customers is our absolute priority, and this behaviour is totally unacceptable.
"The video shows a small portion of an extended incident, in which the two customers in question were being physically and verbally aggressive towards our restaurant team, as well as damaging restaurant property.
"The police were called and both customers were arrested. We have a zero tolerance policy when it comes to anti-social behaviour in our restaurants.”
In November last year The Mirror told of another incident where the police were involved.
The brawl started after three plain clothes officers tried to arrest a man who allegedly refused to leave.
They were called to the fast food branch in London but the Met said he 'refused to engage with them'.
One of the trio of officers was heard telling a man dressed in all black to get on the floor.
But when they tried to detain him, he fought back resulting in chairs being pushed out of the way, items fall from tables and customers moving out of the way.
The incident happened in Wood Green, north London and was posted on an Instagram account.
The Met then said its Directorate of Professional Standards is looking at video footage to see whether the force used by the officers was proportionate.
The fight later spills outside where an unmarked police car with lights flashing can be seen.
One of the officers then uses his baton and the three officers attempt to charge at the suspect.
The video ends as the man who was being arrested goes towards the other side of the road, trying to flee the officer.
