I'm retired accountant so it's a reasonable assumption that with the revision to tax rules, whereas pensions from other countries are exempt taxation, unexplained lump sums are possibly not unless you can show it's a pension lump sum. Banks are required to report transactions above 50,000 baht to the Thailand Revenue, so you might have to explain the source of the 800,000 and whether tax has already been paid on it. It's something that might have to be considered. There's no reason to turn to insults
