Please stop giving bribes to traffic polices. Other than the fact that it's illegal, I'll give you several more good reasons why not.
So the next time you pulled over, be honest and be firm. Apologize and ask for the summon. Play dumb when they ask "macam mana nak tolong?". Do not ever pull a smart comment or else you'd get yourself into even more trouble then need be.
