35% on pensions which are tax free in their country of origin! I'd be opting for Cambodia in a milli-second if that's the case. Thailand is pricing itself out of contention as a retirement destination. F**king ridiculous!

You got ripped off too. I had a hernia operation done in Cambodia in 2019 for a total of $US450 but was in and out in a day. Turned out to be the more serious femoral rather than inguinal. Generally travel insurance does not cover hernias treating them as an existing condition, so if you were covered, you were extremely fortunate.
