Proper Cell Phone Use

I know we are in a society now where we feel we have to always be connected.  You can't go anywhere without your phone.  Home, work and play, phone must follow.  That being said, I feel there are some situations that warrant not talking on your phone.  I was in the bathroom at work the other day and heard someone in the other stall.  A minute later I realized he was actually talking on the phone while he was taking a shit.  Really?  Your conversation couldn't wait a few minutes?  To me, that is totally disgusting.  I wonder if the person on the other end knew what he was doing during the conversation.
