My first two urologists were from India. One of them, after a biopsy, thanked me for being a good patient. LOL. His nurse explained to me that I didn't yell out in pain and frighten other patients in the waiting room. The other doctor, whom I helped find a layover hotel next to Don Muang, commented in my medical record what a "fine gentleman" I was.
Yes, it seems Thailand is getting some undesirable characters with low social standards.
I have never been to Pattaya either, but have seen the same kind of YouTube videos you have mentioned.
