Something odd, BHP recent promo through LINE giving RM5 vouchers for petrol (minimum spend RM30), I've used it 2 times already. Since I'm kiamsiap, I only pump RM30 using that, the rest of my petrol I will pump using my normal Petron (yay Smiles card) right next door.

Thing is, I swiped the RM30 at their counter (obviously, since need to show the voucher), but based on my calculations I still got this 5% cashback for it. As I recall last time for OCBC Titanium etc. we will only get the petrol cashback based on MCC of the petrol pump, not on swipes at counter.

Anyone can confirm?
