Maybe Mike, maybe...I've certainly encountered plenty of "Hitler Youth" folks who take themselves and their jobs far too seriously in the many times I've crossed a border (or boarded a plane to cross one). I've got lots of examples of them being unreasonable, in lots of countries.
Most recent was in Germany this October at the Frankfurt AM Main airport, when my wife and I went through the magnetometer wearing her belt (which is brass and non-magnetic, she's a frequent flyer too...). The magnetometer did not go off, but the German scurity person said something to her in German. My wife responded "I am sorry, I don't understand." in clear English. The German guard simply repeated herself, more loudly, in German. My wife asked "Sprechen Ze English?". The guard grabbed her belt and began to pull it off. NO attempt to communicate, no permission to touch her person, no supervisor called...
And in the wrestling of her belt off, the guard accidentally struck my wife's jaw as she looked down.
In this country, putting your hands on someone without permission is assault, even the TSA has to ask before they feel you up.
And hitting someone, even by accident, usually requires an apology.
But not that day...and we're not the kind of folks to draw attention to ourselves anyway...
My point: we're not the only ones with morons at the border...they abound...
