I think Schwab in the US is the same) but otherwise it's suggested not to use ATMs in Thailand or only for bigger amounts of money (so the rip-off is smaller in percentage)
If you're US based, use Schwab or Fidelity. They don't charge their own fees, currency conversion fees, and reimburse ATM operator fees. Just be sure to opt out of any DCC offers. Otherwise, some banks here charge a $5 international ATM access fee, 3% conversion fees, and pass on whatever ATM operator fees one gets charged. Quite an expensive way to get money overseas and might even make currency exchanges at the airport competitive by comparison!
