It appears they don't approve of horsing around at McDonald's.
A couple travelling by horse and carriage stopped by the fast food restaurant drive-thru for a bite to eat, but were turned down by staff citing safety concerns.
Debbie Murden, 42, said she had been served in the past in the two-wheeled carriage, but was left surprised when she was turned away, the BBC reported.
"They said it was dangerous," she said. "I'm not sure who they meant it was dangerous for, them or us or other people in the drive-through. But there was no danger there.
"I got in touch with McDonald's head office and asked why, if horses and motorbikes are not allowed through, are there no signs to say so? And why is it different from branch to branch?"
McDonald's defended their decision to deny service, saying that only certain types of vehicles are allowed in the drive-thru for health and safety reasons.
"The health and safety of our customers is our top priority and for this reason we are unable to serve customers in a horse-drawn carriage," the spokesperson said.
"We will ensure this policy is reiterated to our employees so any inconsistency is avoided."
Ms Murden took her horse and cart to another restaurant nearby where she had no trouble being served.
