Mate, stop grasping at straws and being a doom and gloom panic merchant FFS! It simply IS easy to get a licence. And if in the extremely unlikely situation where you're refused from making an application, NO money is lost. Simple as that. Ignore this negative drama queen troll people🥸
How pedantic and exaggerated. LOL. The MAJORITY of offices will do what is legally your right to do. i.e Get a licence. And in the 15 years I lived in Thailand, I can't recall a single person who was refused from making an application. However, if you turned up looking like an unwashed, deadbeat backpacker, you MAY have problems. And in the EXTREME case of actually getting denied from making an application, simply go back a few days later and see a different person or go to another office. But I've NEVER heard of anyone having to do that. LOL
As a foreigner who owns property in Thailand, you need to register your stay at your own house with the Immigration Bureau using the TM30 form yourself. Sorted.
