Similar note, I found I could walk out of class anytime in high school and wander the halls as long as I looked sufficiently stressed. As long as you look like you have a purpose people will not bother you (unless you look like you have a purpose that you aren't fulfilling I suppose).

Yeah, totally. It works for avoiding too much attention from authority figures. I will never forget one time I was having a BBQ in an unauthorized area with my mom and ex-wife when this fat Air Force dude rolls by on his Segway. I turned to them and said "Just look like we're supposed to be here" but both of them, not being very good liars, continued with the deer-in-headlights look that guaranteed the guy started asking questions and eventually got us kicked off that part of the beach.
