Feet on seats are to me a relatively minor matter. I would rather that people keep their feet on the floor, but greater concerns IMHO are, in order.
Will the train turn up.
Will I get a seat.
Will the seat be comfortable.
Will there be a buffet.
Will the heating or air conditioning be reasonable.
Feet on seats being of lesser importance than the above, in my view, though not completely unimportant.
I have been known to place my feet on a seat, but not regularly, and then only after protecting the seat with a newspaper or other suitable article, AND if the train is very lightly loaded.
