She was never called again and treated January 11 as the day she was dismissed, and claimed that it was unjustifiable.
The Cullen family told the ERA they believed Ms Frost had been charging too little, or nothing, for produce, and that had caused losses to the business, which was why they had decided against using her any more.
"They say that no decision had been made on 11 January not to sue her services anymore but that Mr Cullen had formed that view the following day after Ms Frost had allegedly been yelling outside their shop, telling customers she had been sacked and urging them not to give the shop their custom."
ERA member David Appleton found Ms Frost was unjustifiably dismissed and awarded her three months' pay totalling $3324. He also awarded her $7000 for humiliation, loss of dignity and injury to her feelings.
However, he reduced the award by 75 per cent for her contribution to the situation, meaning she would receive only $2581.
"Whilst she may have been giving away produce belong to the respondent to customers at a very low price out of the kindness of her heart, she had no right to do so, and her actions are likely to have damaged the business of her employer," Mr Appleton said.
Neither the Cullens nor Ms Frost could be reached for comment.
