Went into K bank today to pay 5438 baht into Mrs account with the book. Need passport, asking why they need to see passport, which I did not have on me, and was told it's important. Asking why it was important and just got the blank look, obviously no idea. On the way out thought round it up to 5500 and pay it into the ATM machines outside, no ID needed. Why do they insist on it over the counter but not at a machine?
