Sorry but I know what happened.
I had a reminder for the extension 5 days ahead. Went there and the officer said I had not done the 90 days, pointed to the paper at the end of my passport and said 17 days, 8500 baht. After that he asked me the remaining papers.
And I don’t wonder. It was the boss of the office. After I didn’t send 65k every month but sometimes more sometimes less, he said he could manage the 800k, he could do that for me for 25k.
