Regional passengers who have not been screened exit the terminal via a dedicated exit, and then re-enter to be screened before their next flight.
Aircrew generally come in for extra attention by security staff. It's called the 'tall poppy syndrome'. Nothing like a good dressing down in front of the passengers.
Have a look around next time you have nothing to do at the airport and see how many trades people there are wandering around. They are always building something. Do you think they go through security with all their tools?
