The Daily Telegraph reported Trump visited the restaurant in Feasterville, Pennsylvania, where he cooked fries in one of the deep fryers and served customers at the drive-thru.
The dine-in restaurant was closed to the public for the visit, but the drive-thru remained open.
“This is fun, I could do this all day,” he said, after serving a customer from the drive-thru window.
“I wouldn’t mind this job.”
Donning a McDonald’s apron, he asked an employee: “Do I take off my jacket? The press wants to see this.”He was then instructed on how to cook and season the fries, reported The Daily Telegraph.
The Republican presidential nominee and former US President was campaigning in the state of Pennsylvania for the entire day.
Trump and Democratic presidential nominee, Vice President Kamala Harris, continue to campaign in battleground swing states ahead of the November 5 election.
