Entering the Library

Here at the University of Wisconsin, one cannot enter Memorial Library without showing a campus ID. I just ran over there to get a book, showed my ID to the ID-checker, and was told I could enter. I then spotted something I wanted to pick up at a stand a few feet away, and stepped over to get it. This took less than 30 seconds. As I began to enter the library, I was stopped and the ID-checker demanded to see my ID before entering. I guess I'm not particularly memorable =)
