(University) During our tour in Córdoba we stopped to buy snacks and use the bathroom. I think that this photo shows the courtyard of the university where we stopped.

I should mention that there are few, if any, public restrooms in Spain, To be permitted to use a restroom in a restaurant or bar along the highway you must buy something. The cheapest item to buy is a bottle of water. Usually you could get a bottle of water for 100 pesetas which was less than a dollar. In more expensive areas you had to pay 200 pesetas. At some point during the semester one of the students caled this buying of water in order to use the restroom the " water cycle." The student called it that because you had to buy water in order to use the restroom, but each time you drank the water that you bought you had to use the restroom again.
