I gotta be honest. I find my travel briefcase (iPad, keyboard, chargers, headphones, pen, ink, notebook, travel documents) to be inconvenient to stow in a Superliner Roomette. I wouldn't store anything so important in a public place for both theft and misadventure, but shuffling it around the room is a hassle.
The one thing I really universally wish Amtrak employees, on a large scale, would learn how to say "no" better. I also wish more of them would say yes when they can with more consistently.
But even some of the better ones seem to need more training in how to say "no". It is almost always a little gruff, frequently a little acrimonious (Soft or worse implication of either how dare you ask or why are you so dumb as to ask), and rarely comes with explanation or appology.
Example: Can I have more water?
Wrong: No, passengers are only allowed two bottles per room!
Right: I'm sorry, but there's a new rule, which I personally think is foolish, that limits us to giving you two bottles, and I have to inventory it. I wish I could, and you might want to write customer relations to complain.
One leaves a much better taste than the other.
