Modern Parables: The Parable of the Eaters

I think if the parable of the sower were to be told in America today, here is how it would go:

There once was a restaurant owner who opened his doors promptly at 7 AM each morning for his many customers. There were many who came to enjoy his homemade biscuits and gravy at breakfast, grilled chicken salads at lunch, and pork chops for dinner.  But there were 4 customers who came by everyday, for every meal (their office was just around the corner).
The first loved to sit in the restaurant, but rarely ordered any food.  He loved the atmosphere, the ambiance, and the fact that daily arrivals at the establishment meant that he could continue to hold his title as mayor of the eatery on FourSquare, but if you were to ask him his favorite item, he honestly could not tell you. He rarely ordered anything off the menu.
The second had sampled every item on the menu.  In fact, there were times when he would order 2 or 3 en-trees for lunch.  It was not unusual for him to have the table filled with plates, even though he ate alone.  Yet, he was not a big man, for after each meal he went to restroom to purge his body of the food he had just eaten.
The third customer was quite obese.  Sampling the entire menu was something she did on almost a daily occasion.  Her difficulty in naming her favorite food was that she loved it all.
The fourth customer also loved the restaurant and ate there daily.  She was in shape and tried to carefully select items from the menu that provided her with a balanced diet.  For her, exercise was just as important as eating healthy.

Now here's were I would like to ask for your help.  What would be the application or meaning of each of these? I'll share my thoughts later this week with an update of this post.
