A woman was refused service at a McDonald's drive-through amid safety concerns over her vehicle - a horse and carriage.
Debbie Murden, 42, was turned away from a branch of the fast-food giant in Alfreton, Derbyshire, on Saturday after staff said it was unsafe to serve her.
But she said she often took her Welsh Cob and carriage to other restaurants, and later the same day was served by a different fast-food chain.
Miss Murden, from nearby Pinxton, had said she was served by the same McDonald's that refused to allow her to use the drive-through just a few weeks before.
But the company said there were safety fears, as the lanes are built for cars, vans and trucks.
A spokesman said: "We're very sorry to have disappointed Ms Debbie Murden and for any confusion caused.
"Our drive-thru lanes are custom built for motor cars, vans and trucks.
"They are extremely busy serving a large number of customers every hour, therefore our concern in this instance would be the safety of both the horse and the customer. We will ensure this policy is reiterated to our employees so any inconsistency is avoided."
Ms Murden told the Nottingham Post: "My horse travels on dual carriageways and is never affected - there is no reason why it would be dangerous.
"It was a surprise to me as I've never been refused before. We often stop off at pubs and leave the stallion in the car park, it's usually no bother whatsoever, and is mostly a good talking point."
