Can I get a 7-day extension at Samui Immigration after my SETV has been extended for 30 days?

The post inquires about the possibility of obtaining an additional 7-day extension at the Immigration Office in Samui after already extending a SETV for 30 days. The comments clarify that while an official extension can be denied, one can pay a fee (1900 Baht) for this processing and receive a 7-day 'extension denied' stamp, which allows for an additional week in Thailand.
