CELLPHONE CONVERSATIONS

Is it really necessary to hold a 15 minute cellphone conversation (using your "outside voice") of idle chit-chat while seated in a relatively quiet restaurant?  So, without any effort, you can hear everything that person is saying.  That's what I experienced today.  That has to be one of my biggest pet peeves!  Not everyone is interested in your cell phone conversation!!  I just think it's about one of the rudest things to subject everyone else to your end of the conversation.  Same goes for those people who use cell phones in a movie theater.  RUDE!
