Yesterday I used the Aeon atm on the second floor of the Electronics Plaza (Siam TV?). I withdrew 9,000baht with NO 150 baht service fee. Also I checked online with my bank and the exchange rate was very good @ 30.20 baht to the US dollar. Compared to the quote from Siam City Bank of 29.05 baht per dollar for a cash advance, which I declined, I'm glad I used the Aeon atm. BTW I happily returned the extra money & more to the Thai economy at the Sunday night walking market!
