My experience on the SWC was of a conductor who was not tolerant. A drunk, loud, and abusive guest in the dining car got moved to the SSL until we arrived at the next station. (This happened soon after we had left Los Angeles, so that was not a long period of time.) When the train stopped, the guest became combative when the conductor and the trainman tried to remove him. Another rather burly guest came to their aid and got him down the steps and delivered to the police waiting. Not sure why the police didn't board the train to help the Amtrak staff.I think one clear and direct warning should have been enough. At that point you can tell if they're going to take it seriously or not. As soon as it's obvious they don't care or can't control themselves it's time to go. Not sure why this conductor felt they needed two chances but glad things ended on a positive note.
