And yet another tale of woe from someone denied entry to thailand due to inability to show 20K baht in CASH at the airport.
They showed the funds in their bank account when they bought their tourist visa in Vietnam BUT were under the false impression that once they did that they would not be asked for proof of funds when stamping into the country. :O
One more time, let this be a warning to people who have extensive entry histories to thailand on either visa exempt or tourist visas BE PREPARED to meet the 3-proof-ofz, or at least the proof of funds (20K baht or the equivalent in CASH) when you're flying into the country using Suvarnabhumi or Don Mueang.
Here's their denial of entry stamp and you can see the thai number two ๒ as the reason they were denied.
This also appears to be a receipt for one nights stay at the lock up at the airport before they flew back out to Vietnam.
