Either fully open the country up or don't bother - if you cannot open to locals how on earth can you open to foreigners, and your anti alcohol CCSA dinosaurs along with anti drink Prayuth should all resign, it is clear you have no clue what you are doing, it is embarrassing to watch
you may personally have views on alcohol consumption but you need to realise that it is an important integrated part of tourism and many social and entertainment structures, you cannot stop it so get your heads out of the sand and face reality
Get the country open again - you claim 70% of people will be fully vaccinated by 15th Oct, lets plan for that in Hua Hin and Pattaya and get things fully open to locals first, increase testing in those areas to monitor the situation then if all is good open to foreign tourists 1st Nov, this cannot go on forever, and drop the anti-alcohol nonsense - stop trying to force your personal ideals on the rest of the population - keep it to yourself
