Not forgetting school canteen has very low rental, unless the school is trying to make money nowadays. Could it be some organisation trying to takeover the school canteen business?
Some of the kids in my nephew's school are getting $30 a day. Dun ask me why. The kid end up buying his friends drinks and meals. Sometimes even movies. There is one had never been to a hawker or even food court. The first time was with my nephew to the food court. He sat there waiting for a while and asked, "where is the waiter?".
