MILFORD - A Connecticut executive will be the focus of an episode of ?Undercover Boss? airing on CBS this Sunday.

The show follows Don Fertman, Subway's chief development officer, in disguise as he learns what it takes to work the counters at Subway stores.

Fertman says one of the hardest parts was keeping up with the fast pace. At one point, he says a manager pulled him off the front line because he was going too slow.

He says he has not seen any of the footage yet, so he will be gathering around the TV with his family and friends to watch the show.
