Hello! Just reporting another case of refusal of entry at Suvarnabhumi due to inability to show 20k baht in cash for visa exempt entry. This happened to a friend 2 hours ago and is forced to buy a plane ticket for the next flight back home.
Im sure Tod Daniels can use this as another example (or warning, more likely).
TLDR : Answer Summary
A recent incident at Suvarnabhumi Airport highlights the strict cash requirement for visa-exempt entry into Thailand. A traveler was refused entry due to not being able to show 20,000 baht in cash and had to purchase a return ticket immediately.
