Lunch Time Makes Us Smarter?

Remember when you were in elementary school and you had recess? Remember hearing arguments that recess should be shortened? Or that it wasn't necessary, aren't you going to school to learn? In college, recess doesn't exist. But the social interaction, the fight for the last box of fries, and the elements of cognitive learning make recess (or in our case, lunch) an educational experience. One time I went to lunch with a friend from high school. He and I went for the vegan/vegetarian section for two different reasons. My reason being I am a vegetarian and his being that the cafeteria was full. Since he didn't want to wait a long time, he gladly took the fake steak (portobello mushrooms). After getting our drinks, we head out to the full cafeteria.It seemed as though the rest of the school had chosen the same time to eat. Dilemmas,dilemmas, dilemmas... we asked a guy sitting by himself if he minded if we joined him. He didn't mind, or told us he didn't, so we sat down and happily dug into our meals. After finishing, we went our separate ways. How did any of that make us smarter? We looked around the lines for food and upon realizing that the fastest way to get in and get out with food was to eat vegan. Sure it was a decision anyone could have made, but looking around it was apparent very few people had picked the same route. 
Then there was the obstacle of  finding seats to eat. I seemed as though every table in the Hans was occupied. So we asked a guy sitting by himself to join him. That seems like a simple task. However, the underlying thought process in choosing the table and the person is a complicated one. We had to look for a person who didn't seem to hard to get along with. Then we had to make sure said candidate didn't mind us joining him. We also had to choose someone who looked like s/he wouldn't feel awkward with us joining him/her and like s/he would enjoy/join our conversation.
Then there was the task of actually finding common ground with this complete stranger. Not knowing anything about his (we did sit down with  a guy) preferences, friends, or how politically correct we would have to be around him, we had to carefully choose our words and sentences. After all we wouldn't want to scare him away! We were friends from school with a few inside jokes and background knowledge of each other. For instance, I knew that my companion is a democrat, and even though I am not, politics is not the first conversation anyone would want to start with a stranger. Worse still would be religion, unless we somehow magically landed with a person who doesn't mind. There is a long, long list of topics one should avoid when meeting with an absolute stranger. 
The point to all this being that in multiple ways, a task as simple as eating lunch in a college cafeteria can stimulate learning in multiple ways as well as easy application of what one learned. We learn from eating lunch in ways so minute that we would never be able to make notes on the subject matter or explain what exactly it was that we learned. But the social/conversational skills are necessary for everyday life. Some students may learn even more in the cafeteria then they do in a classroom.
