If you are a security guard, theft is probably not a career-enhancing choice.
We contract with a security company, who send a variety of people to our site. Some last for years, and become cherished members of the team. Others last only a few days or so. One in particular has been with us for several years, but last weekend may have been his last, both with us and with his company.
Our administrative staff keep a variety of foodstuffs on hand for various visitors. It is common knowledge that food put on the cafeteria counter is for anyone, but food in the admin area is for visitors, and you must be specifically offered any before you take it. Well, one of the admins reported to the head of security that food was going missing on weekends.
The head of security reviewed the security cameras. The weekend guard started his rounds, and checked every door in the hallway, which he is supposed to do. The door to the admin area was clearly locked. So, the guard took his keys out and opened it, which he is not supposed to do. He came back out into the hallway, and something dropped from his hand and skidded across the floor. He picked it up and wandered away from the camera, heading towards a trash can. When he turned back towards the camera (which he knows is there, because he monitors it), he inadvertently gave a very clear view of a food bar, tucked in the palm of his hand.
You would think that someone who knows the security of the building would be able to do a better job defeating it.
