Given that the exact same question is the current top post but for driving instead of transit, I feel this question was needed.
My answer: I saw some guys hooking up a Raclette Grill to the outlet in an otherwise empty German intercity rail waggon. They had it unpacked in one of these 4 person seats with a small table. No idea if that could work or if draws too much power from the board net. I just headed on to the next waggon.
That’s interesting. I wonder why?
When you buy products that are deemed sensitive, such as condoms or tampons or hemorrhoid cream or whatever it may be, they also put that in a paper bag instead of the regular bag so that no one can see what it is.
Of course, I found this to be counterproductive because that means you know that person is carrying something “sensitive”.
Maybe with books, that’s why they wrap all of them?
