Food same price if not more, accomodations the same, coffee more expensive, local beer is cheeper but cocktail the same or more. I been in Laos, Cambodia and Vietnam this year and nothing was cheaper,
In Vietnam Apartment is much more than in Thailand, for 250 usd I get a quiet new apartment with Aircon, fan, furniture, balkony in Hanoi the cheapest I saw was 300 usd, most 500+
I not advise against the law, I only say there is no consequences and tm30 is not the responsibility of the foreigner ar all. You keep with your story that dtv is a work permit and nobody else allowed to work remotely 😁 this shows how much you know about law and Thailand
