Times: Student is taken to court after putting her feet on train seat
She had flip flops on. Personally, I think it is okay to put your feet on a seat if you take your shoes off first.
I once went on a coach trip to Austria with my school. The driver told us "If I see your feet on the seat, I will take your shoes off myself." I do not think he did this, but I did not see anybody putting their shoes on the seat.
