A driver who is alleged to have spat in the face of a young McDonald's drive-through worker after becoming irate over an order has contacted police.
The teenage worker had the man's saliva on her face and in her mouth following the argument at the Essendon McDonald's outlet on Keilor Road, police said.
The man became impatient and refused to wait to pay for his order of two frozen Cokes at the first drive-through window about 5pm on January 13.
He was left waiting at the window for between 20 and 30 seconds, while the drive-through operator took another order, police said.
"He's lashed out at being made to wait for 30 seconds," Constable Josh Whitley told reporters on Thursday.
The man then drove the black Mercedes to the second window, where he was told by staff to return to the first window.
However, he refused to move and threatened to block the drive-through with his car until his order was filled.
The man then argued with staff, before spitting a large quantity of saliva at the young employee.
The saliva went all over the girl's face and neck, and also inside her mouth, police said.
Police had contacted the owners of the Mercedes, but they initially refused to say who was driving the car at the time.
The driver contacted investigators on Thursday afternoon, after media reported the incident. Police expect to interview him in the coming days.
Constable Whitley said the teenage worker was "quite shaken up" over the incident.
"Verbal abuse is bad enough, let alone it becoming physical. I think it shows complete lack of respect, and arrogance."
Constable Whitley said he understood the man had only ordered "a couple of frozen Cokes".
"It wasn't a difficult order to wait for," he said.
Constable Whitley said the girl was waiting for the results of medical tests.
