I've only seen it at CVG.
Worst part? CVG's problems weren't the massive lines in security, they were apathetic personnel at security that wanted to have a 60 second conversation with each and every person and demanding each individual crewmember wait behind the line until they wave you over like a dog.
I wouldn't be surprised if they demanded crewmembers get down on all fours, put a dog buscuit on all of our noses and command. "Noo... no... no.... wait.... wait... wait.... GO!"
Yes I'm serious and no I'm not drunk...
Well, at least not yet... It's only 2330!
