I wonder if AnaTravel asked for an afternoon tea and they put together something not on the menu for her. That would explain the sandwiches and the scones.
This makes me think that often when I'm in the CCR, I often don't want a sit-down meal. If I have say 30 minutes, a drink and a healthy snack is what I'd like, particularly if I'll be dining on board. An afternoon tea actually sounds good. I'd also like some canapes or fresh nibbles. This means I can have a relaxing sit-down, a drink and a small bite.
