Parking officers in Bath are to be equipped with body cameras because of the high number of incidents of abuse and violence on the city's streets.
One man has just been ordered to pay £860 after one confrontation in the city centre.
In the last year, there have been no fewer than 38 incidents of violent or threatening behaviour directed towards Bath and North East Somerset Council's civil enforcement officers.
In the most recent case, 34-year-old Gary Day, from Trowbridge, was fined £705, and ordered to pay £85 costs and a victim surcharge of £70 under the Public Order Act 1986 for causing harassment, alarm or distress, and using threatening, abusive or insulting words or behaviour or disorderly behaviour.
Chris Major, group manager for transport and parking at the council, said of the 38 incidents: "These incidents are simply because CEOs are doing their job.
"This behaviour is unacceptable in any walk of life. The recent prosecution marks a point where the council will be more proactive in co-ordinating action with Avon and Somerset Police when people overstep the mark.
"The behaviour we are talking about is not a brief remonstration with an officer after someone receives a ticket. The cases recorded involve a sustained tirade of vile abusive language and physical intimidation. If someone receives a ticket and thinks that the council is in the wrong, there is an appeals system where we will consider grievances and rip up the Penalty Charge Notice if considered legitimate. All we ask is for people to be respectful."
However Mr Day, who is the director of electrical, plumbing and heating engineers Gem Solutions, said he felt the system was unfair and that traffic wardens were simply out to make money now, instead of educating people where to park.
He said: "The parking officer was hidden between the van and a house.
"Our vans and shop are clearly named, so usually they knock on the window and ask us to move before issuing a ticket.
"Parking in Bath is very restricted, and we were not doing any harm at 7.30am, the drivers only pop in to pick up keys and forms - about 15 minutes at a time.
"I know that parking officers are there for a reason, but it seems to me that they are more interested in making money rather than educating people and telling them where to park."
In his defence Mr Day said that after initially insulting the parking officer he had walked away, but became more angry when challenged by the traffic warden to repeat his comment two more times.
On the third time he was unaware that the officer had his radio on, and was broadcasting his comments back to the control room.
Mr Day said he was sorry for his comments, but felt there should be more give and take.
He said: "I have apologised for it, but the parking officer did not conduct himself in a very professional manner.
"We have ten to 12 vans out on the road every day serving the community, but the parking officers see it as ten to 12 chances to give us a ticket and make money."
All the officers will soon be equipped with body cameras, similar to those used by many police officers, which can record at the touch of a button. Such technology is already working successfully in Hampshire, Leeds and Cardiff, with the number of attacks reduced by up to half in some cases.
Mr Major said: "If a CEO senses an altercation, the persons involved will be informed the body cam has been switched on. They can make a considered choice about their behaviour. People have nothing to worry about if they behave appropriately. But if someone is abusive or threatening, they could end up with a criminal record and hefty fine."
The latest fine followed an incident in Nile Street last October, with Mr Day pleading guilty to the charges.
Sgt Anthony O'Brien of the Bath city centre police team said: "We fully support parking enforcement officers who must be allowed to carry out their work without fear of retaliation. As this case shows, we will take legal action against anyone who offends against them."
