A McFlurry-loving horse's owner was fined after she marched the hungry animal into a local McDonald's.

Christine McGrail and daughter Olivia tried to go through the drive-through with a horse, but were refused service, the Daily Mail reported.

Restaurant managers told the unusual crew they could not wait in line with the other cars, and to order inside.

McGrail claimed the horse had been served there before, so she took it "literally" when the staff invited her inside.

McGrail, Olivia, and the six-year-old pony named Minnie, all entered the restaurant to get some lunch.

As soon as they walked in Minnie defecated on the floor, prompting McDonald's staff members to call the police.

McGrail admits her actions were "rash," but insisted the horse had been allowed to use the drive through before.

"Minnie likes McFlurrys. We've genuinely been served several times before and I didn't think using the drive-through would be a problem," she said.

The U.K. woman was fined £90 ($138).

"The staff refused to serve the women due to company policy," the Greater Manchester Police's Whitefield branch said on their Facebook, according to the Daily Mail.

"The women then took the horse into the restaurant who ended up doing his business on the floor. The sight and smell of this caused obvious distress and upset to customers trying to eat, as well as staff members. Officers arrived at the location and woman was issued a Fixed Penalty notice," they stated.

The "no horses in the drive through" policy was put in place to protect customers in the event the horse was startled. 

 "I can confirm that on 20 July a woman allowed her pony to enter our restaurant in Whitefield after being refused service in the drive-thru lane. The incident caused distress to customers and disruption for the restaurant and the police issued the woman with a Fixed Penalty notice," a McDonald's spokesman said.

"The incident caused distress to customers and disruption for the restaurant and the police issued the woman with a Fixed Penalty notice. The health safety of our customers and staff is our top priority and for this reason we are unable to serve pedestrians, bicycle riders or customers on horseback through the drive-thru," he said.
