Joe,
Don't eat the food there unless it has improved a lot. I used to have to spend hours there when I was working and made the mistake of eating at one of the spots in the terminal. After that I killed time by going into the arcade section and then back through the scanners and carrying a big book that had circuit pack schematics in it. Every time through the security people would look through the book, ask me what that stuff was, and then ask me if I understood it. One of them after looking at some of the book told the other one that he was glad he was to dumb to have to understand that stuff and could just be a security guard which required only a little thinking.
