yea but they could have followed through with the Phuket idea, where they planned to section off a part of the beach. Could have and would have encouraged some tourism to the region.
did you pay for your ASQ in Phuket? Without the direct flights to Phuket, you may face problems. I know people who have crossed land border from Cambodia and were able to arrange a car to take them from the border to their ASQ in Bangkok, but it was expensive. You may be able to arrange something from bkk to Phuket (although unlikely).
Thais still need to eat. So if it’s a restaurant aimed at the Thai market, that could work. Maybe leave it a while to see what happens with the current Covid situation.
