What can I expect when applying for a visa extension in CW during COVID-19 restrictions?

I went to CW today for a visa extension based on COVID-travel restriction and got the 60 days straight without having to go back after 2 weeks. I was on Non-B prior to covid-related reason extension so I've been doing my 90 days notification at MTT on separate dates (online is not working for me after my Non-B was cancelled). I observed that IOs there were already asking for the TM47 (90 days notification) receipt and collecting 2000 baht fine for those who have none. I've witnessed 5 people under different IO experiencing this while I was waiting for my officer to finish checking the usual documents I gave him (took him 10-15 minutes to finish, which I think was oddly killing time). So just want to let others know what could be expected if you do your extension in CW.
