Subsidized Petrol

My BIL is running a "Water" business; selling water filters and selling all kinds of water. In this business, you need a truck to transport the water filters and water everyday. In order to save cost on the petrol, he applied for petrol subsidy from the government. I am not so sure how much is the subsidy but what I know is for RM33 of petrol, they are paying about RM28 only. That is RM5 discount. Wah! I wish the government can give petrol subsidy for SAHM. ;)
