What are the 90-day reporting requirements for expats on a multi-entry retirement visa in Thailand?

The user, living in Thailand on a multi-entry retirement visa, shares their experience regarding the 90-day reporting requirement after returning from a trip to Laos. Although they typically avoid needing to report by leaving and returning before the deadline, they learned after a recent return that they were required to check in with local immigration within 20 hours. An immigration officer noted that violations of this rule could incur fines ranging from 5,000 to 10,000 THB, though they let the user go without penalty this time. The user seeks advice from others who might have had similar experiences.
