I agree XCard. The problem is I don't belive I have ever seen this rule enforced. As a coach I usually try not to get worked up with the official unless it is a call that truly merits questioning. The problem comes when your sitting across the mat from coaches, similar to those mentioned above, who question and complain every single call that does not go their way. The referee allows this to continue and you end up feeling you have to start playing the same game just to get a fair shake. There is an easy soultion to preventing these circus like atmospheres, that is enforce the rules! If you get up and question a call, and your wrong, WARNING. Do it a second time, TEAM POINT! No exceptions. If all officials enforced this rule reguarly I think this would deter some coaches from arguing even the simplest calls in an attempt to manipulate the officials.
