Pro-Tip: NEVER EVER trust an immigration officer INSIDE the country about anything to do with thai visas sold outside the country
AND
NEVER EVER trust a thai consulate offficer OUTSIDE the country about anything to do with entering the country or getting visas inside the country.
The consulates are run by the Ministry of Foreign Affairs and they sell visas outside the country. They have NOTHING at all to do with the entry requirements OR what the immigration rules are INSIDE the country.
With that being said, you should be okay BUT there are no guarantees. Be prepared when you stamp into the country with your proof of funds and proof of onward travel. Remember just because you have a visa in your passport doesn't mean you get stamped into the country. It just means IF you get in you get stamped for the days that visa gives you
Good Luck
