Here's a thought for you about this rule: verbal actions out of turn are binding
Player A is contemplating his action with AA, Player C acts out of turn and says "raise", the dealer tells him its not his turn, player A sees this happens and decides to take advantage of the situation and puts in a hefty 10 x BB bet. Player B folds. Action to Player C, now according to the rule he would have to make his "raise" of the previous bet which was 10 x BB. Which he probably doesn't want to do.

[Insert sinister laugh from player A]
I have always dreamed of this situation with some of the fish that play at my game.
What are you thoughts??
