"Exaggerated yawning" What the heck is that? If I have
an early morning flight I may be guilty of this.

"Excessive complaints about the screening process" I never
complain on the way through. I always wait until I can log
into FT to launch into a complaint.

"Widely open staring eyes" Not unless I see something that
catches my undivided attention which rarely happens given
I'm old and have seen just about everything.

"Wearing improper attire for location" So, big deal... I arrive
in Canada wearing t-shirt, jeans and boots when it is 20
below and snowing out. I came from Texas! I will bring
my hat next time ok?
