Cell Phones on the Dinner Table

Total bullshit. I've never understood the point of this, your pockets arent big enough, or you cant feel the cell phones vibrations? To me, it says to me that my dining companion is always ready or hoping that someone will call so they can get away from our dinner conversation. Its horribly rude to take a call at dinner in the first place (this is old news, everyone should know that) but still this gets the assignation "Double Bullshit".
