My favorite is in IAH when I get the 3-hour EUA on the way in and am notified by email, go ask the PC agents if there's any chance of clearing an upgrade on this segment, they tell me it's "checked in full."
I then say, "I know, and I'm one of them. Just reprint the pass."
When confronted like that, they often make up an excuse. "Oh, I was looking in the wrong place," or something like that.
I believe CO was talking about moving some of the kiosks inside security for people to look at stuff like this themselves. It would eliminate this problem.
