A realistic vertical 9:16 video, first-person POV, action camera.
Cold winter morning, breath visible.

An older American man in his early 70s cleans tables at a highway rest area.
He wears a heavy coat with a U.S. flag patch and a veteran hat.

The camera wearer asks:
“Did you serve?”

The man replies quietly:
“Yeah. Years ago. Just working.”
