If service is more than average, $5.00 per person, per day on a long haul route is not a bad guide. On my most recent trip, Portland-Chicago on the Empire Builder, the attendant was not the friendliest, but he kept the sodas & coffee stocked, made the room up punctually & gave us a couple of small bottles of wine at the end of the trip. $20.00 seemed more than reasonable.

I think we are saying about the same thing. I am assuming that our Aussie friend is traveling solo and the Coast Starlight is just a one night trip. Hence, either $5 or $10, depending on the quality of the service.
