I asked SCB (more than a year ago) if they would do a counter withdrawal on my foreign debit card and they said they can't do it. I only asked at 1 mall branch and didn't ask at a larger SCB branch. TIT, so it's very likely you will receive a different answer at a different branch.
Krungsri, according to another AN poster, does not charge for MC debit cards but when I showed my VISA card they said the fee would be 200 ฿.
