since the very first day i start visit hc long long years ago, i hv written down my real name and nric num. As mentioned by lot of bro, if the place get raid, when the officer ask you why u didn't write down the real info, how u going to answer them? of course, you can say go health centre nothing wrong, but to the officer they may tell u writing wrong info maybe wrong as u maybe trying to hide something....
so to be safe, just write down ur real name n nric num.. after all if got raid, the officer may and still can record ur real name when they are for ur ic...
thanks
