i think the prob is :
when a person is getting off the bus, he/she will be
concentrating to move to the exit point and then the card reader,
then try to walk/run down the high steps...if you notice, pple dun
walk down slowly and carefully, step by step...they simply quick
shove to the exit, tap card (head will turn to left/right). when
look back to see the steps, the mind may not be fast to acknowledge
(slow down), the person is already doing the skip skip skip down
the steps, so, stairs slippy, shoes worn out (no grip), falls....
he BLAMEs BUS.
now another scenrio, person walking at the shopping mall, no
rail to hold on, with grocery bags, walk down the stairs fast, slip
and fall, BLAME SHOPPING MALL?
even on the road, while looking out for the cars, dashed across
the road, slip and fell on the road divider, BLAME
LTA/CONSTRUCTION/government?
one day, if the person missed the steps @ stairs at own home,
will they blame their parents and themselves? nah...oh, they
got maids to blame...
