Deborah Mason, of Pitcher Street, Port Campbell, pleaded guilty in Warrnambool Magistrates Court to unlawful assault and recklessly causing injury.

On December 12 last year, Mason attended the Coles supermarket in Warrnambool's Gateway Plaza about 3pm. The 53-year-old female victim was at the service desk of the supermarket inquiring about the price of an item.

The court heard Mason became frustrated over the delays at the counter and swore at the victim before telling her to hurry up.

Mason then stood in front of the EFTPOS machine, preventing the victim from paying for her items.

The victim attempted to nudge past Mason, who pushed her in the chest.

The victim fell to the ground after failing to break her fall with her hands.

She lost her shoe, hit her head on the base of a shopping trolley and cried out in pain.

Mason said: "I can't take this" and left the supermarket, leaving behind her groceries.

The victim was taken to Warrnambool hospital with a fractured wrist which required surgery.

During a police interview on January 1, Mason told police the victim was being ridiculous, stupid, and making her feel frustrated.

When asked if she felt threatened by the victim, Mason said: "I have been interviewed by the Syrian army, I don't get threatened by people."

Magistrate Peter Mellas said the victim had ongoing hospital attendances but looked like she would make a full recovery.

Mason was convicted and fined $1000.
