I guess the old lady does not know much about China. This drama will never happen in China. In China, the elderly do not ask for a seat. Neither is there a need for labelling the priority seats. It is because, in China, a young citizen on any seat would give it up for a senior citizen standing nearby without being asked, and the senior citizen will node and smile (thank you) before taking the seat.
