They were "shocked someone in the public eye would treat someone as abhorrently as he treats someone who's just trying to help him", before warning others working in the service industry to be wary of dealing with Eagle.
Eagle told Fairfax he was talking to a panel-beater on Friday afternoon about getting his car fixed when "some guys give me lip" outside his Newtown electorate office, blocking his path.
"I was swearing at them, they were swearing at me," he said.
Eagle offered a formal apology for the incident, which he called a misunderstanding, saying he was keen to go back to the panel beater and say sorry in person.
The Herald has approached Eagle and the Reddit user for comment.
