Last night I landed at DTW at about 11:30pm.
Saw two things as I exited the sterile area that had me shaking my head.

At this hour there was NO one going into the sterile area, just some folks leaving. The first was a young female blue shirt that was "dancing" into and out of the metal detector to get it to beep.

Back and forth, back and forth......beep, beep, beep......

The second was a young male blue shirt who was sitting at the exit to make sure no one was trying to go in the out door. This guy was rapping to himself:

"Booming like a stereo, like a radio, boomin!"

Actually he didn't sound to bad, if you like rap....

The two of these young people should get together, they could form an interesting floor show.........
