Do you know how to tell if an MLCer is lying? They're breathing.
Ok, I'm sure this is an exageration....well, maybe.
I don't know how you would be able to inforce that. What you do have control over is what you do if you find he's had a PA. You have the option to ask him to leave at that point. Btw, you do realize how much power you do have right? It's had to remember that when you're operationg out of fear and walking on eggshells.
