lonebird,
I guess you could say that anyone can say anything they want out of turn, but in poker, they could be held to that action. Rule #29 Verbal declarations/Acting in turn are easy to understand. Players must act in turn: to me that means if they don't, there will be consequences. I really think there are too many details that are left out to make a good decision. Was it pre-flop? Was the other player the small blind? I question wether I would allow a raise from a player that said he was folding, only to be told that he was the big blind and was already in. I am assuming this is the situation and if I am correct, in my opinion the BB could only call. The action must have been backed-up to the proper player for the BB to consider a raise, right?
To answer your questions; I think that you were right when you said that it was not okay, and I know you are wrong when you say that a player can say anything they want just because they are out of turn.
That's the way I see it,
