Can I extend my Thai visa for an additional 7 or 14 days after already extending for 30 days?

A user inquired about the possibility of extending their Thai visa for an additional 7 or 14 days after already extending their stay for 30 days. The response indicated that obtaining another extension after a 30-day extension is likely to be denied, and they might instead receive a 7-day stamp which requires a fee. Additionally, it's suggested that some immigration offices may require proof of an exit ticket to grant this stamp.
