No, it's not the naughty word - it's the arrogance to think that you can bawl someone out in public and get away with it. Yes, I agree it can be annoying and inconsiderate when someone hogs the 'stage' but that's not the way to deal with it unless you want a full-scale brawl on your hands - which is exactly what would have happened (and frequently did) if you'd shouted at someone like that in a Hull docklands pub on a Saturday night.

A good MC can handle situations like that in a diplomatic way.
