They run the experiment twice — once with a female couple and then with a couple of men. The diners in the restaurant are unaware that the family and the waitress are all actors. With hidden cameras set in place, I was surprised at what I saw. 

The waitress has been given the task of agitating the gay family, and she goes as far as trying to get other customers to help her tear this family down. It's interesting seeing how different people respond to the situation. The best part? Seeing what one Texas man wrote to the gay couple. Be sure to watch the video for this touching moment.
