I watched it. It would be interesting to know how many times they filmed it to see if everyone reacted not just the people that they showed on the show.
My guess is, most who ignored it wouldn’t sign papers to allow them to air it. But....they could have said “out of A times the actors performed this, B times nobody stepped in.”
I wonder how far they let it go though. Did the kid actually eat it? Did people ignore? Watch for a reaction?
I thought of some people here...who wish their child had grandparents like the ones in the diner.
