Shoot, I'll get in my two cents but I'll probably just state what someone else has already said.

When I eject a manager I make sure he leaves. If for some reason I notice that he has come back or later or is relaying messages then I stop the game and warn that unless he's left the park in one minute the game will end.

The "let the coach come sit in the stands in street clothes" thing doesn't work at the parks in which I officiate as there aren't a lot of bleachers. Even the high school parks aren't big enough for the coach to go sit in some far off corner of the stands. For me he needs to be in the parking lot far removed from his teams bench and any players.

This has been a very good subject though because I thought the debate on whether the ump has the right to forfeit a game was very interesting. Both sides made good points.
