According to police Korrinne Anne West, 30, of Moad Place, assaulted the employee at the Bathurst Road store of D'Aquino's Liquor on April 21, 2018, after a female co-accused she was with was refused service.

Police said the co-accused attempted to buy a bottle of bourbon and two bottles of cola but was refused service when she couldn't produce any identification.

West then entered the store and attempted to buy the same items but the attendant refused her service, because she thought she was trying to buy them for the previous female.

After another woman was also refused service for the same reason, West and the co-accused re-entered the store and confronted the female employee and West threw a bottle of wine at her, which rebounded off the victim's shoulder and smashed on the ground.

West continued to yell abuse and a male employee told them to leave, but as she was walking out West pulled a bottle of port off the shelf, damaging the top of the bottle so it could not be sold.

The female worker received a bruised shoulder and sought counselling because she began to feel anxious whenever she had to refuse someone service.

West was given a custodial sentence of a seven-month supervised intensive correction order with conditions she undertake rehabilitation and abstain from alcohol for assault occasioning actual bodily harm.

Magistrate David Day also fined her $110 for the property damage and ordered her to pay D'Aquino's Liquor $39.98 for the damage.

"A bottle was thrown at the victim, it struck her, luckily it didn't strike the victim breaking the bottle as to cause a laceration," Mr Day said.

"I don't think she's low risk, I think she's a time bomb who will go off again unless she's supervised."

On the same evening of the assault West became involved in a fight with another woman in Sir Neville Howse Place at 9.30pm.

According to police, who were in the area for an unrelated matter, West and the other women pulled each others' hair and wouldn't let go even after falling to the ground.

Police had to physically force them apart and said West appeared to be well affected by alcohol.

For the affray, Mr Day sentenced West to a 12-month community correction order with conditions of rehabilitation and that she abstain from alcohol.

Solicitor Lucien Gration said the offences were out of character and West said she didn't have an issue with alcohol. "She doesn't drink everyday, she doesn't drink to excess," Mr Gration said.
