 The problem is that it says "for coaching purposes".  If the guy is on the phone with his wife b/c she wants him to pick up some milk on the way home from the game, that doesn't seem to be a problem by rule.
But, of course, how do you know?  I think you just say he can't use it on the bench.  Feel free to use it in the hallway, just not on the bench.
