Come on guys, cut the Air Marshalls a little slack, a lot of 'em got suckered into leaving their exciting jobs with the Border Patrol, where they got to exchange gunfire regularly with real criminals.
It shouldn't come as any surprise that 40+ hours a week of modern air travel will drive 'em a little squirrelly.
Surly FA's, airline "food", delays and misconnections wasn't quite what they expected.
