Loved your answer to the company director. I'll have to remember that one.

The one I used that got the most thought from a directors was: "Directors have access to more sensitive data that anyone else in our business. If anything, I need to ensure that you follow the security procedures even more than our other staff."
The response to that one was a complaint to the Head of IT which is where my earlier comment of "I am trustworthy and this is why I earned my position" came from. Needless to say I was told to just relax the security for this case.

Let's just say I wasn't pleased. Perhaps if I'd have had "Is this a test?" in my arsenal, the outcome may have been different.
