How long do I need to be out of Thailand for a visa run on an exempt visa?

The user inquires about the duration one must stay outside Thailand to obtain another visa exempt entry while on an exempt visa. Responses clarify that there is no mandated time you must be out of the country; you can return the same day if leaving by air. However, note that re-entry is ultimately at the discretion of the immigration officer, and it's advised to have proof of accommodation, cash, and onward travel.
