Why was my request for a single re-entry permit on a Non-O retirement visa denied at immigration in Koh Phangan?

The user, holding a Non-O visa based on retirement from Phetchabun, encountered difficulties obtaining a single re-entry permit at the immigration office in Koh Pha-ngan. Despite explaining their circumstances, the officer insisted on the need for bank statements, leading the user to question the legality of this requirement. Comments from the community suggest that the officer's request for additional documentation might be justified since the visa was not issued at that location, and alternative solutions, such as purchasing a re-entry permit at the airport, were also proposed.
