Who really cares? If the business doesn't want you to place calls within "their" property, abide. The same with hospitals and churches. Cell phones are like a 3rd ear now. People are rude usually when using them when they are out and about. Like at a restaurant and someone is talking to another person on a cell phone while dining with someone else. Or in a church where they are praying...that too would be rude. In a hospital it might interfere with other equipment causing someone damage. I say let the property owner have the discretion to jam them. I'd like to "jam" boom-boxes on the beach too. 5,000 boxes all playing something different at the beach is beyond annoying, especially when people like to set the volume at 10.
Trying to explain courtesy to a self-centered nitwit is incredibly pointless. They know full well that the world, the universe, revolves around them.I personally prefer making fun of them. I was in a very nice restaurant and a nitwit was screaming into his cell phone and telling someone what everyone at his table had ordered. So, I started loudly telling him what everyone at my table ordered so he could relay that valuable information. He got upset and people in the rastaurant started laughing. It would be so much more resonable, to have a sign at the door that says, "Your cell phone service is unavailabe in this busines." And, those who would go into shock at the thought of not being connect to their cell service could go to McDonalds for dinner and Starbucks for a funeral. I just imagine a funeral. Solemn organ music playing. A closed casket in the front of the room. And suddenly, from the casket comes the William Tell Overture Ring Tone.
