Back to the subject though, observed a Security Staff member who had just entered the secure area undergoing the explosives check. Made me feel less inclined to feel picked on.
Two reasons:
1. It provides a zero for the equipment to check it is working. Often if they get a positive they will test themselves again to check that the equipment is not just putting out false positives, to do that they need to check that they are clean first.
2. It provides an easy tick in the box when they are adding up how many people were screened.
Anyone else noticed that some of the screeners have visitor ASICS? Seems a bit suss to have someone doing that job who has not yet passed their own background check.
