Discount 20% for 80 times per month Toll payment?

What a joke. Suprise! I don't expect Najib know how to make a joke, but he is. For 80 times to take place, you must pay 4 tolls each day on everage in order to get a discount. After all, it only effective on September. Get pass through more toll booth in order to get discount? The sentence should be phrases something like this: If you pay toll more than RM80 per month, you'll get a 20% discount, which I think more practical.... Isn't it? as simple as that... Do they still think that we are dumb enough to be fooled off?
