It's always satisfying catching out our friends, the public relations experts. After all, much of the time it seems their job is to provide an impenetrable barrier between inquisitive hacks and their clients.
But when even the PR won't answer calls you can be sure you're on to something.
Take a recent case in point. I call an agency back who has already put in some confusing calls to us. I'm put through and wait patiently only to hear loud and clear: "Can you tell him I'm in a meeting?".
It gave me great pleasure to answer "Er, they can't, I'm right here."
