Walker, who launched his presidential campaign on Monday, recently gave ABC News’ David Muir a tour of his old Golden Arches stomping ground in his hometown of Delavan, Wisconsin.
While visiting the governor was reunited with his old boss, Rita Butke, who now manages the location where they both worked in the mid-1980s.
"He did good, he did good," Butke said recalling Walker's performance at his high school job.
The presidential hopeful glad-handed with cashiers and line cooks. He even took a turn at the drive-through window.
"Boy it brings back memories,” Walker said.
And, of course, Walker ended his trip down memory lane with a hot bag of McDonalds grub to go.
