ON "PRIMETIME: WHAT WOULD YOU DO?," FRIDAY, MARCH 25

What will happen when a waiter drops food on the floor and then serves it to an unsuspecting diner? Will anyone say anything when an agent yells at her super skinny model for ordering something fattening at a restaurant? Some cases seem to cry out for action, while others seem to present a choice. What would YOU do? Using hidden cameras, "What Would You Do?" establishes everyday scenarios and then captures people's reactions. Whether people are compelled to act or mind their own business, John Qui�ones reports on their split-second and often surprising decision-making process. "Primetime: What Would You Do?" airs FRIDAY, MARCH 25 (9:00-10:00 p.m., ET) on ABC.

This week's scenarios include:

· Race Appropriate Toys: A landmark study conducted in the 1940s, and cited to support desegregation in Brown v Board of Education, showed that a majority of black children showed an inherent preference for playing with white dolls over black dolls, identifying with the white dolls and displaying a poignant disconnect from dolls of their own skin color. Fast forward to 2011 - what happens when a white child opts for a black doll and vice versa? What if the caretakers for the children begin admonishing the children for their choice of dolls? Will anyone intervene?

· Waiter Serving Dirty Food: When a waiter drops food on the floor and serves it to an unsuspecting couple sitting in a booth, will anyone warn the couple or say anything to the waiter? Twist: Will anyone say anything after they hear how rude and obnoxious the couple is to the waiter? Video preview: http://abcnews.go.com/WhatWouldYouDo/video/eating-food-off-floor-13194929

· Cheating Husband: When a travelling businessman makes his daily Skype call to check in with his wife, he says all the right things - telling her he misses her and that he hates the marathon meetings he's been stuck in. Unfortunately, the other customers at this internet caf� are seeing a much different picture. What they know and the wife doesn't, is that he has a woman with him just off camera� and the only business they're up to is funny business. Will customers step in to say something to the man? Maybe even get in front of the camera and out him to his wife? We then reverse the scenario to see how people will react to a woman having an affair on the road.

· Too Thin Model: An already thin teen model type is berated by her agent to eat less. When the young woman tries to order something other than a salad, the agent scolds her. Will anyone intervene? Video preview: http://abcnews.go.com/WhatWouldYouDo/video/thinner-dropped-13202957
