There are lots of cell phones out there. But there seems to be no real convention regarding cell phone etiquette.
For example, every body sort of whispers in church or at a funeral-nobody really needs to be told this after childhood. It is rare to see adults violate this convention.
Most people wear a shirt in a public place, unless they are at the beach.
Etc.
But when it comes to cell phones, there is still no established convention. People may or may not remember to shut them off in a theater, restaurant or church. People talk, in public, into the phone or (worse in my opinion) a Bluetooth earpiece, in a voice much louder than a normal conversation. Very few people seem to consider going outside, or into another room to carry on their conversation. Most people do not seem to even consider letting the call go for now, and getting back to the caller at a better time.
How long until social convention catches up with the technology and there is a clear standard of cell phone etiquette?
