The last few times I applied it was done in 2 days, apply in the morning, pick up next afternoon. On the pick up day I checked out my hotel and went straight to the embassy, my taxi driver waited for me outside and took me the airport for my flight to Bkk, I was back in Bkk by 7pm.
Anyway it’s irrelevant as this is all pre-Covid, I’m concerned about post-Covid.
