This video shows the moment a driving instructor pulled over and launched a barrage of abuse at two schoolchildren just for riding their horses along a road.
Craig Allred, 52, can be heard shouting: "What gives you the right to let your horse s**t on the road?" after becoming angry by the mess made by the animal.
When young rider Callum Mullock tried to explain that he and friend Megan Lockett, 14, who filmed the incident, couldn't ride the ponies through the privately owned fields alongside the public road, Mr Allred replied: "I don't care about your horse".
The 12-year-old countered this by saying: "Well, we don't care about your car", with the youngster expressing his fear that the angry instructor might try and "run us off the road".
He said: "He was very angry.
"He said that we shouldn't be riding on the road. I was a bit shaken up after that I didn't know what he was going to do.
"I said to my friend I thought he might try to run us off the road.
"Usually people are quite understanding of horses.
"It was a very quiet road, not many people around.
"I know that there was another person with him, he got in the passenger side."
The expletive ridden video, captured on Friday in Martland Mill, Greater Manchester, has since been viewed around 50,000 times on social media.
Mr Allred, of Leigh, joined the AA Driving School three years ago but has been fired from the role since the clip emerged, with Callum's auntie Tracy Cumberbatch, who posted the video, slamming the instructor for his behaviour.
She said: "I have owned horses for 30 years and I have never seen behaviour like that.
"I know that some people don't respect horses.
"There's no chemicals in horse muck and no law in the land that says you have to pick it up.
"What was this guy's problem?"
Confirming that The AA's franchise with Mr Allred had "ended" a spokesperson for the company said: "We were disappointed to see this behaviour, which in no way upholds the views and values of the AA or AA Driving School.
"Driving School instructors are franchisees and are not directly employed by the AA.
"However, this has been investigated as a matter of utmost importance and appropriate action has been taken.
"We apologise for any upset, particularly to the two children, who dealt with the incident in a mature and commendable manner.
"The roads are there to be shared safely by all and we teach pupils how they should interact with horses as well as other road users.
"Of course we expect our instructors to follow that advice."
Mr Allred declined to comment on the argument, adding that the matter was "all being dealt with internally by the AA".
