Nonsense. If most Thais wore masks before Covid I must have missed that. Perhaps 0.5% of Thais ever wore a mask, especially indoors prior to January 2020.
I don't recall ever being served by a mask wearing shopkeeper, supermarket clerk or even immigration officer before 2020.
Thais love masks because they've been conditioned to wear them. Not because they were used to wearing them before 2020.
In fact, before 2020, those working in professions where wearing a mask would have been beneficial or made sense (such as, while working in dusty environments) rarely took such precautions.
I remember having some masks with me to put on while helping to lift some bags full of plants full of fine soil dust, while the Burmese laborers who work in that environment never wore one! This was in 2014. I would put on a mask for the 2 minutes it took me to help lift these heavy bags onto my truck.
Now the situation is reversed: Thais mindlessly wear masks in all situations despite not being warranted anymore.
The Cambodian grounds keeper in my moo baan now wears a mask (often under his nose) most of the time, whereas during Covid restrictions, he rarely did! It's like he started wearing the mask all the time, around July 2022. That just doesn't make any sense!
