Phone Etiquette

I watched a video about cell phone etiquette on Media Shift and very much agree with much of what was said about a time and a place for cell phones. The one thing that bugs me the most is when people talk on their cell phones in a resturant. This bothers me because I am a waitress and I hate it when I go up to a table to take their order and they are either on their phone or they start ordering and there phone rings and they tell me to wait a minute while they answer the call. I think that during a meal or while at a resturant your phone should be put on silent, or at least vibrate so you can enjoy your meal, then you can resume your busy life afterwards.
