Who does this diligently?
I DO! Raise hand.
I bet most do too. Hahaha
But not all are equal.
My favourite one is still Tony Roma's. RM10 off for a minimum of RM30 spent is a good deal. Very good deal for me. Sometimes, the RM10 is more compared to whatever credit card discount they offer.
p.s must find time to go to Tony Roma's soon. Been craving for their ribs for ages now! Especially their lamb ribs. Nyum nyum
