"Testing" Security

[Condo Guard]

I had a supervisor do a similar exercise with marked playing cards (so nobody could cheat). We did it when the building was empty and quiet. The guard who found the most cards on his rounds got a prize (nothing fancy, usually just a free fast food meal or a dollar store flashlight).
He had the same rule - the cards would not be "hidden" or placed in anything dangerous (i.e. inside a high voltage electrical box, for example). Everybody liked it except for one guard, who said it was "demeaning" and "hokey." Oh well...

[Trunk Monkey]

I had one site supervisor that used to hide rubber worms all over that site and threaten to write up any one that didn’t find them. There was a fish pond in the lobby of the building and every one I found went right into it.

The supervisor I have now doesn’t put signs out on me very often because every time he comes on sight I’m out doing my rounds. If I was sitting in the office he’d probably put out a few more.

There's a limit to the effectiveness of this sort of thing because people who are preoccupied with looking for rubber worms might very easily miss a real threat.

On the other hand, if your site actually is under threat of attack by rubber worms (as I believe many are), it makes perfect sense to test you with them. I'd use gummy worms, though, so you could have a little snack when you found one. I prefer positive incentives over threats, like "I'll write you up". Guaranteed that officers would find more of my gummy worms than his rubber ones.
