I hate this too! I was on a date once and the guy actually put his hand up to the waitress to "hold on", while he was talking on his cell phone! Rude! People who talk loudly on their cell phones in public places so I can hear their entire conversations and don't even notice the "evil eye" that I am giving them! lol There is nothing ruder than trying to have a conversation with someone and keep getting interuppted by their text messages!!
