If this SS agent even so much as grunted about the crew checking and re-checking his I.D. then he should have been sent down the road kickin cans.
The number of daily checks that uniformed crew members go through in a day is ridiculous. Take my boots off, undo my belt buckle, search my bag... excuse me, but do know that as soon as I clear your little check point I am going to my jet where there is this really neat CRASH AXE at my disposal! And no, I don't mind if you take my nail clippers... those things can be really dangerous - I might clip the Captain to death, but don't worry about that crash axe!
My favorite is the I.D. check at every station. Picture this... Top of the world, dark, blowing snow, -30. The CSA comes up and checks my I.D. I still have not figured out what exactly we are doing this for? I don't believe in little green men, but maybe they think that an alien got me while in cruise when we flew over the arctic circle? Or maybe if some bad guys were in the back, they were able to take over the cockpit, land the jet on that small runway after doing that non-precision appraoch, and they are still doing their best to stay on schedule so it is up to the CSA to catch them?
As I said before, if I have to go through this every day at work (probably for the next 28 years...) with a smile on my face, then that SS agent better be nice and say thank you sir for the ride. Attitude is something he is not entitled to.
Safe skys to all.
