ABC News' Tara Evans reports:

Will shoppers step in when an underage worker is berated by his boss at a specialty foods shop? Will anyone notice he's working illegally?

"How long does it take you to stack cheese? It's not a Sudoku puzzle, it's stacking cheese.  Let's move," the overbearing manager said.

"He's 11 years old, he shouldn't be working here at all.  On top of the way you treat him.  You don't talk to him like he's a piece of garbage.  Are you kidding?" said one woman to the manager.

What the woman didn't know was that our underage worker and his manager were actors-and that she was right in the middle of a "What Would You Do?" scenario staged at Salpino's Market in Wantagh, N.Y.

How far will shoppers go to set the manager straight?

Watch a passionate reaction below and see the complete scenario play out Friday on "What Would You Do?" at 9 p.m. ET.
