To the above. This is the ministerial regulation as in the Police Order:
5. In the case where an alien applicant does not meet the full qualifications stipulated by the criteria herein or in other cases not specified in this Order but a competent officer equivalent to or higher than inspector is of the opinion that the alien has legitimate reason for staying in the Kingdom of Thailand, the application shall be forwarded to the Commander of the Royal Thai Police or an authorized competent officer for further consideration of the alien's application.

So I will presume that, while the 'competent officer' has the 'discretion' to waive most of the nominal requirements, he/she cannot waive the fee schedule.
This was a Act promulgated (1979) by the late King Bhumibol and as such specific requirements as enacted cannot be treated as such piffle.
