No no no, I don't wave at the walls.
Only the cameras.

I am not in the least worried about looking suspicious.
An advantage of having nothing to hide,
and plenty of time before my next flight.

Sometimes a secondary is more entertaining than the lounge.

Two agents grilled me in LAX coming in from SIN on a CMB run.
This was because I had NO checked luggage, not too heavy.
Flipping through my passport endlessly, one stares at me,
says "You've got a LOT of stamps in your Passport".

Silence. "Uh..What was the question ??"

At IAH agent grills me, gives me the stare, and says,
"Do you have any Weapons of Mass Destruction ?"
His stare breaks into a big grin, he says "Get outta here. Welcome Home".
