Well.....not to overstate the obvious , but.....be sure the curtains and/or shades are drawn and/or pulled down.
Seriously......
For real, people can forget to do these things in the room, esp. if they are traveling for the first time in a sleeper and are not familiar with the gadgets.
And, yes, people can see inside.....so....
I remember, as a child, a dignified-looking well dressed lady was slowly removing every stitch of her clothing in a roomette with the shade all the way up while the train was parked in a station. I guess somebody got her attention, don't remember...I just remember the funny part, and everybody else thought it was funny, also.
Those shades in a roomette out to the hall are easily over looked. Even if you have nothing whatsoever in mind, just don't want everybody to walking down the hall to look at you. you want to stay aware of them.
I grew up riding a different type of roomette when the only way you saw outside in the hall as through the open door. I find those hallway shades a little disconcerting to this day, and sometimes I forget about them.
