Police prosecutor Sergeant Garry Wilson said that on June 18 Wilton was across the road from the victim's workplace about 8am and started yelling at her. "She became increasingly abusive and aggressive," he said.
She followed the woman and her friend into 10 O'Clock Cookie saying as she followed them "don't walk away ... because you know what I'm going to do to her", Mr Wilson said.
As the pair tried to sit down at a table Wilton pushed the victim's wallet aside, the court heard. The confrontation spilled onto Queen St as the women left.
Judge Walsh said while there were no actual threats of harm, both women had been frightened. "They were scared and intimidated by your actions. Your conduct had adversely affected both of the victims."
Wilton clearly had an alcohol problem, he said. "You need intensive help ... I hope it goes well for you."
