In the US, that seat would be occupied by some junky that spends all day getting coffee thrown on him, as he begs for money to buy fentanyl. He's usually going through withdrawals, so as soon as he dozes off he probably $#its all over the seat... When someone gives him some food, he promptly pukes it on the other half of the nice, comfy seat... When the train stops, he gets up and pisses in the corner of the car, and slings his $#it covered underwear in the aisle.
