Before Milad Mirghahari began posting videos on TikTok, he didn’t know his job at Subway could be deeply captivating to millions of people. His parents, both immigrants from Iran, bought their first Subway franchise more than twenty years ago, and later opened a second store in Cedar Grove, New Jersey, near their home. After school, Mirghahari would eat a sandwich while his older brothers worked. At sixteen, he followed their lead and took an official part-time position.
