3 would bring it back to where it was before which we know is doable even serving coach. When I rode the few times I did before they flexified it was chef LSA and 1 server in the viewliners on both meteor and crescent. No food specialist. I guess the million dollar question is can the LSA handle all the non cooking work. Maybe on the Star with just 2 sleepers, no coach passengers, and the fact that there are no purchases other than alcohol. I would tend to agree with the consensus that 3 is needed for good service especially on the meteor with 3 sleepers.
They did just put out another job posting for train attendants for Miami. This is the job class they’d need more hiring in to add server jobs. The jobs done by train attendants are coach attendant, sleeper attendant, and diner service attendant.
