I agree--there are a couple of those guys in my meeting... and typically they ramble about stuff that seems irrelevant to the topic at hand. But they don't usually exceed 5 minutes, so it's OK.
I can just go with it for the most part, unless there is a new person in the group, and I worry that that might turn THEM off if it is their first Al-Anon meeting. It would be a shame if they never went to another meeting because of one errant attendee.
I do think the business meeting is the time to bring it up, and the group "leader" if you have one can maybe tactfully handle it with the offending person.
PS, Cyranoak, yes, I hate to be sexist, but both overbearing guys in my meeting are "dudes." The dudettes are usually apologetic and more inclined to pass when it's their turn to speak. Just sayin'....
