Signs of Rubber

[SAump]

I had a spectator behind the backstop watching the game curiously walk toward the nearest dugout in a hurry after the opposing coach requested time and pointed out the spectator's position.

I did feel something "dirty" was going on behind my back but I didn't know what to do about it. How was an umpire suppose to eject a quiet, disciplined spectator when an umpire is not suppose to concern himself with what goes on behind the backstop? I still am not sure what penalty I should have imposed. I have showered but the memory of the event lingers.
