And that's one of the bigger reasons for assigned seating failing the first time they tried this. People who didn't realize that they had an assigned seat, mainly those used to Metroliner First Class, just picked any seat upon boarding that they wanted that wasn't already occupied. And FC attendants not wanting to anger pax for fear of no tips, refused to enforce the assigned seats. I suspect that Amtrak will have a very hard time once again getting the attendants to enforce the assigned seats.

Of course one thing that the attendants didn't seem to consider is that those of us who had picked our seats and found them occupied and had an attendant just tell us to sit anywhere there was space were often less inclined to tip because we ended up in a double seat facing backwards when we had reserved a forward facing single seat.
