I think he could get better, cheaper food on Sentosa.
Are you sure it's not a case of: 'you are pork-loving infidel and I don't like your face, so I charge you extra' situation? It happens more often than you think.
What is so wrong for charging more money? No money stay at home, go to your nearest garden or park and plug grass to eat.
Beware, NEA will be activated later, SInkies are once again fucked!
Also, enjoy the prices now, they will skyrocket further in this moneylaundering hub.
Maybe in future you want to buy food but they have no more food to sell you. Or the SGD becomes totally worthless, food have to be rationed out with coupons.
