Philly Pretzel Factory CEO becomes 'Undercover Boss' Friday

When Dan DiZio sold pretzels on Roosevelt Boulevard and dreamed of opening his own pretzel bakery, he didn’t know what the word “franchise” meant, or that having one store could ever happen. But now with 120 locations nationwide, the CEO and co-founder of the Philly Pretzel Factory will be on “Undercover Boss” Friday night (8 p.m., CBS 3).
