Singapore Kindness Movement general secretary William Wan was spot on when he said that signs to indicate priority queues create the norms, but people have to act according to them ("Priority queues for platforms and lifts in all MRT stations"; last Friday).

While I support the Land Transport Authority's latest initiative to further promote gracious behaviour among commuters, I have my reservations about its effectiveness.

I have observed that the signs reminding commuters about the priority and reserved seats on trains have been blatantly ignored over the years. Hence, I reckon the same fate will fall on the move to have priority queues at the MRT platform doors and lifts.

The problem is also prevalent in supermarkets and foodcourts, where seniors are unable to enjoy priority queues and reserved seats respectively.

I believe that a lack of stringent enforcement has resulted in such a state of affairs.

Organisations which come up with such signs must not treat them as decorative items, but ensure that they produce the desired outcomes.

We would do well to be reminded of the good maxim that "anything worth doing is worth doing well".
