These people are awful
I dont get what kind of a person would not show up for the final date. What is the advantage of not showing up? If you don't show up you hurt someones feeling and worse look incredibly shallow to the rest of America. How cold is walking out anyway vs confronting people. I dont understand the reasoning behind not showing, its not like you are signing up to marry them, you can very easily let them down during the date after.
Obviously if all people showed it wouldnt be very good TV, but I dont see the reasoning.
