A police employee has been charged after a brawl inside a Woolworths supermarket in Western Sydney.

An argument broke out between two male shoppers at the store in Auburn about 1.20pm yesterday.

It started with a shove, then a kick, before a two-litre full cream bottle of milk was swung, smashing and splashing everywhere.

The milk went all over a cashier. 

“I feel bad for her the most,” one witness told 9News. 

A woman who was with one of the men involved in the argument jumped in to help.

“The wife’s a true one straight out, my wife better do that for me too,” a witness said.

“I was very happy to see the wife jump in for the husband. I thought that was great,” another said. 

Woolworths confirmed the incident, telling 9News that “there’s no place for violence like this”.

“We continue to assist police with their inquiries ,” a Woolworths spokesperson said. 

A 34-year-old man, who is a police employee, and the woman he was with have been charged with assault and affray.

A 62-year-old man, also involved, suffered minor injuries.

It is unclear what started the brawl, but shoppers condemned the wild scenes.

“That’s just ridiculous, we shouldn’t be doing this in public places,” one said.

“People are throwing things around. It’s too much pressure. People need to calm down,” another said.
