seems this roger poh and many brainless sinkie dont understand singerlis . priority seat means that when ALL seats are occupied ,
and those classified as priority person has the right to required able body person to give up the seat.
but if there is empty seat nearby , that "priority person" should sit there , no insisting to sit at the "priority seat" .
but stupid sinkies take it to mean that "priority seat" cannot be occupied by normal person. and "priority seat" should be left empty
throughout the journey even though no disable/handicapped person is on the train.
no wonder 60% keep asking to be screwed every 5-year.
