What dugout does the visiting team sit in during a baseball game?
Their own. Generally if they sit in the home team's dugout, there's bound to be a fight or two. Seriously, it varies from stadium to stadium. Often the home team is on the 3rd base side, with the visitors across at 1st base. But there's no hard and fast rule. Sarcasm does not seem appropriate for answering a question.
The rules with Managers being ejected from the game is that they cannot remain in the dugout so they have to go into the clubhouse after the point of their ejection. However they are allowed to watch the game from stadium seats but they have to be in civilian clothes and cannot be close to their team's dugout.
