What happens if the accommodation owner doesn't complete the TM30 when leaving Thailand?

The discussion addresses concerns about leaving Thailand when the accommodation owner fails to complete the TM30 form. Most users clarify that the TM30 is primarily the responsibility of the property owner and is not a barrier to exiting the country. Various comments emphasize that border immigration does not require TM30 for departure unless one needs to interact with immigration while in Thailand. It is highlighted that the typical consequences for non-completion might involve fines, but this is irrelevant for exit purposes.
