How could you not agree with this rule. Not only does is help to deter cheating, it also cuts down on the chance of an annoying interruption during games. The tournament area should be as quiet and distraction free as possible.
I swear to god some people don't know how to read.
So because it only prevents some cheating, and not all cheating, it's not a good rule?
The rule that was quoted has nothing to do with cellphone use in the playing hall. It has nothing to do with the tournament hall whatsoever. So it has nothing to with cutting down on distraction when playing. There are already rules that address that. Reading a couple of sentences isn't that hard.
Actually there was no quoted rule. thirdstreet posted below a rule without quoting it. I had to go find it just now.
Or perhaps, when leaving the board, the opponent has the option of starting your clock and accompanying you wherever you may go.
