There is lots of hostility to ill mannered people using cell phones in public places! I totally despise mindless gabbling, where you can't escape, or the bad manners of people of all ages who seem to think their affairs (literal as well as figurative) will interest all within hearing range. They even raise their voices, so everyone can hear. How nice! Just walk past some loud mouth jerk with a cell phone and push the kill button it solves the problem every time.
