Some airports send the PAX back to the CP to have it done and others have screeners that are sent to the gate. There are cases where the CP screeners dont mark the pass to show that it was done and therefore, it gets done again. This really pisses passengers off.
I have seen cases where the ticket counter computer lets the passenger have a BP that has no SSSS on it and the computer at the gate says that they are SSSS. I have seen PAX that come from connecting flights and go to the gate for the next leg and the computer at the gate says they are SSSS and they have never left the sterile area. Random gate screenings are not done anymore.
