According to my time, my PC dont allow us to take cab and alight at the terminal, reason is because if everyone take cab to the terminal, it will cause the traffic there to jam, as those who are from tekong knows, there are 2 lanes only, a on-coming and on-going...
but after all,its alright to take a cab and alight at the terminal once in awhile, if you are late....
you can do anything and everything, but just dont get caught!!
