Most of the time, making your way through airport security is a mind dulling affair.
The abrasive fluorescent lights lull you into a depressive haze while the whole energy of the airport feels like a well-secured purgatory. By the time you're taking off your shoes and neatly stacking your laptop in a plastic bin, all feelings of being alive have melted into a grey abyss, and the employees paid to X-ray your items often share that same sense of ennui.
Conversely, because security is so often boring, those rare times when things get spicy feel extra memorable. In some cases, it's something as simple as a funny exchange, a bizarre item scanned, or a misunderstanding over what an object's use is. But the added stakes of airport security heighten the drama of whatever does go down.
