He was the president or director of the Pittsburgh Zoo Society. And he taught a class on, his class was on revenue. And we had a class where we learned that you had to pop popcorn all day so that people smelled it and would buy more, and you had to oversalt it so they’d buy soft drinks. That was a class. Another class was a guy came in and demonstrated how to use a cash register. That was a class. So the classes were kind of interesting. However, the class that I learned the most from and used what I learned for years was a gentleman whose name I have long since forgotten, but at the time, he was the human resource manager for the San Diego Zoo.
