exactly. A rubbish definition with no practicality for the customer.
I got screwed out of a "dining" promotion before when the restaurant I ate in was classified as a bakery by Visa/MC
- No obligation to clarify beforehand what a particular expenditure may get treated as
- Online bill payments and AAVS get lowest tier cash back (0.4%)
- if it falls in multiple categories, first it goes into lowest tier , then online spending (4%), then local supermarkets (2%), then overseas/local spending (except e-wallets, 1%).
But the point is that this should be an internal cost to the bank, not passed to customers. HSBC does not pass it on. SC passes it on, I'm not sure what other banks do. It's really a stupid charge, buy in HKD with a HKD credit card and still get a 1% charge just because of some internal mechanism whereby the payment is processed offshore.
With AMEX no such charge
