If you use Skyscanner and find a cheap fare on one of the booking sites they show.. don't every use any of them.. go directly to the airlines website. Many of them are shady companies. Even Google flights shows you such sites.
In just saying these kinds of people were never wearing masks outdoors or indoors as I've seen.. they are anti social elements that are not good for Thailand
The stupidest reasons are no reason to not follow the law in a country where you're guests. You're lucky they don't deport law beakers like those who keep posting ridiculous excuses.. I guess you're the same kind of people who drive drunk.
