Potentially suspicious behavior could include wearing heavy clothes on a hot day, sweating on a cool day, loitering in the terminal without luggage, or even using a pay phone.

Those pay phone users have always freaked me out.

Seriously. Who doesn't have a cell phone these days? Very suspicious, indeed. I think this could be "series" -- "HUGH," even!
