Sounds like a fun job
You can say that again! Sitting around in your Ops 4X4 (WTF?) waiting hopefully for some unsuspecting handler, cabin crew member or pilot to pass you by not wearing their ear defenders or high viz or committing some other minor, utterly trivial misdemeanour so you can joyfully nab them and present them with a ticket or worse confiscate their ID pass. Complete halfwits, many of them!
