What should I do about my 1-day overstay in Thailand?

An individual is seeking advice on how to handle a 1-day overstay in Thailand before their flight. They are concerned because their visa extension ends on March 26, and they have already overstayed one day. The comments provide mixed advice, suggesting that fines for minor overstays (e.g., one day) are usually waived or minimal. Some recommend going through immigration on the day of departure, while others caution against overstaying entirely.
