Funny how the immigration office lady over the phone failed to mention that. She asked if my motive was whether I didn't want to pay the fine. I mentioned that it was because I wanted to follow the rules and do things properly which she then mentioned with paying the fine as you exit is the proper thing to do.

Also remember that it is not a 72-hour visa-free transit but should be stated as "up to 72-hour visa-free transit depending on your next flight" In my case, I was only give 24hrs but since I stayed 48hrs, I was in breach of the law. When I asked about the 72hr rule, they went on a tangent about how everyone would come here and visit for 72hrs if that was the case.
