If you flew in the 1970s, 1980s, or 1990s, you remember a very different airport experience than the one we endure today. You remember getting on a plane without taking off your shoes. You remember breezing through a relatively quick metal detector. You remember walking off a plane to find your loved ones waiting for you in the terminal. If you're a little bit older, you might even remember a time where there was essentially no security at all. You just took your ticket to the desk, checked your luggage, and had a cigarette in the airport bar.
Some of that convenience was stripped away incrementally but, after 9/11, things really changed. These days, no one can wait for you, you have to take off your shoes, stand in the giant x-ray box, put all your gear in 3-4 different bins, and watch helplessly as TSA agents grope your wife, your child, or your grandmother for no apparent reason.
