Today, I withdrew 30,000-baht, from the AEON ATM machine in Thailand (which, at this time, did not charge a fee). [Thailand no longer has fee-free atms]. My checking account statement shows an ATM withdrawal for $975.58.
On the street today, the best rate I saw at the money exchange booths was 30.5 (baht/USD).
When you divide the baht I received by the amount that I was charged, you will see that I received a better-than-street rate of 30.75 (baht/USD)!
