Which Immigration Offices Near Bangkok Are More Lenient for Tourist Visa Extensions?

Certainly there are some strict and unkind immigration officials, and there are some who are just easier to deal with, more lenient.

I need to extend a tourist exemption which means I can go to an immigration office anywhere in Thailand as long as I stay in a hotel the night before.

I'm an American citizen (haven't been to the US in two years), but I'm worried about negative attitude due to the recent spike in coronavirus cases in the US (now around 3000).

So my question is this. Does anyone know where immigration officials tend to be more lenient, less strict, just easier to deal with? Particularly in towns north of Bangkok?

This probably could only be answered by someone who has been here awhile and has some intimate knowledge and experience. Anyway, much appreciated, if anyone might even be able to answer.
