Let me guess cloth masks (entirely pointless but the main used ones in Thailand) or surgical masks (mildly helpful if you have Covid in reducing particle spread if worn properly and changed every couple of hours, entirely pointless otherwise or if wet).
The only ones with any real benefit for those healthy are properly fitted (no beard, no gaps) N95 masks which are uncomfortable when worn properly, even moreso in hot weather).
So which ones they wearing at Makro because 99% of mask usage in Thailand is entirely or largely pointless?
