TSA officers are, at least at face value, the demographic most profoundly unaffected by holiday cheer. As a traveler, it's hard not to feel like these agents exist to make your travel experience as unpleasant as possible. It’s the Friday before Christmas and you didn’t even really want to visit your uncle in the first place, but here you are, standing in the security line being yelled at by a bunch of surly folks in blue. Take your shoes off! Remove laptops from bags! And for god’s sake, take everything out of your pockets!
