not as much as we think. Thai banks really don’t make much on foreigner customers. Basically No loans or mortgages, no credit cards interest, foreigners not qualify to buy many of the insurance products, etc. etc.
The customer Service Representatives don’t want to spend time helping us because they cannot make any commission and the pressure to make quota does not change due to dedicating time to foreigners
However, I opened a Krungsri account today with passport, non-o extension stamp, cell phone bill digital copy sent to bank email, TM-30 digital copy sent to bank email.
