And, to be clear, it's a crappy job. Get up ungodly early to travel to a work site in the middle of nowhere to shepherd thousands of jumpy/tired strangers* through arcane procedure (possibly in a language that they don't exactly have a firm grasp of) in the hopes of catching the one-in-a-million who has shown up specifically with the intent to kill you and as many other people as possible (or so your training says).

All while gaining basically no transferrable skills.

*Also, a significant portion of these strangers are headed to destinations and experiences you could never dream of affording or having the opportunity to access.
