Seriously only a turd who is a Singaporean don't know the GST
rate
He should just go kill himself or something
He's just wasting earth resources and oxygen
anyone who has actually purchased anything from a shop which issues
receipts (except from hawkers i think) would know the rate.
and if he really doesn't know...can check on the official
webbie. but no, no, he doesn't trust the webbie and prefers mouth
of word method. some more prefer's ditzy's word.
