So I got slapped with a 2% surcharge recently.

Not wanting to argue, I quickly to down the terminal issuer and made copies of the tax invoice and cc slip.

Made a total of 4 complaints ( a new record ) to

1. Issuing bank's cc
2. Merchant's bank
3. Central bank of Malaysia
4. Customs department as well.

Hope it will teach them a lesson. :/

Depends on terminal rental agreement.

And honestly, most shop's margin is roughly 10~20% if not they won't be selling

Don't care whether they lose money or not, I don't see this practice being done in countries like HK, US and UK.

What you see is what you pay. No such BS as need to cough up extra.
