(I’m eating in the mall food court when I see an angry man approaches a security guard. It looks serious, so I try to listen to their conversation. I only hear a few fragments.)

Angry guy: “Security alert…suspicious item…chemical spill…At other places, the security staff works in conjunction with the local police, bomb squad, and haz-mat team! [Nearby military base] is pretty high on al-Qaeda’s list of targets. I don’t feel safe at all!”

(The angry guy stomps off. I’m a little worried at this point, so I walk up to the security guard.)

Me: “What’s going on?”

Security guard: “Nothing. Somebody left an open can of Coke in the middle of the floor.”
