A new video appears to show also taking on an Australia Post worker.
In the video being shared on social media, the woman visits a post office without a mask and informs workers "I do not need [one]".
"I suggest you update yourself on what the Department of Human Services has put on with regards to masks and who needs to wear them," she says.
An Australia Post employee calmly serves the woman as she berates him.
Residents of metropolitan Melbourne and the Mitchell Shire must wear a face covering when leaving home unless they have a lawful reason not to.
It comes after a store, claiming it was against the law and her human rights to force her to wear one.
Stores like Bunnings operate on private property and have a right to make requests of customers, including that they wear masks.
On Monday, Australia's Deputy Chief Health Officer Nick Coatsworth said it was "disturbing" to see people attacking others who are doing their job.
"It is not a human rights issue to decide not to wear a mask," he said.
"I just can't see how it takes away someone's human rights or individual liberty to just have to put a face covering on at the request of government. It is simple. We know it's effective. We know it's the time to do it."
Dr Coatsworth praised the overall efforts of Victorians to stay home or wear masks when out in public.
"It sounds so simple. We realise it's difficult. The quicker we do that together the quicker the curve will bend down the other side," he said.
The CEO of the National Retail Association Dominique Lamb called the woman "inconsiderate" and said shops like Bunnings are able to refuse entry to those without a mask.
"Human rights have nothing to do with being asked to wear a mask. At this time it is about safety, consumer safety and retail worker safety," she told the Today show on Monday.
"What they're asking you to do is comply with a direction that has come from the government and that particular direction can be enforced by police within Victoria … They have to keep their other workers and other consumers safe."
"Unfortunately during this period we have seen an increase in some locations for retail crime which includes customer abuse, customer assaults, and other theft issues."
She said there had been a 17 per cent increase in violence against workers.
On Sunday, Premier Daniel Andrews also slammed the woman.
"If you are just making a selfish choice that your alleged personal liberty, quoting something you've read on some website - this is not about human rights," Mr Andrews said.
"There are 10 families that are going to be burying someone in the next few days. Wear a mask."
Police said on Sunday that 126 fines were issued in the past 24 hours.
Twenty $200 fines were handed out to people for failing to wear a mask, including to a man and a woman who refused to give police details when they were stopped.
