Work at a new hotel nearby just continued, but not with the full crew. And plastering the ceiling standing on a bench at 15m height didn't seem very sensible to me and the man on the photo still had to finish two floors higher up.
Only the pubs were closed, meaning they shut their doors, but in a lot of places inside, drinking was still going on as usual. I even saw an open air bar where everybody drank their favourite (alcoholic) beverages out of coffee mugs. This morning and this afternoon I saw Thai people buying bottles of beer at a convenience store which despite the regulations against buying or consuming alcohol in public, effective today didn't seem to cause any problems.
