Not true. Anecdotal evidence from walking around the streets and malls etc of Pattaya indicate that many, many white foreigners (I'd say about 70%) do not wear any mask whatsoever, and, when given a questioning cursory look/stare, react aggressively. They know exactly what the issue is, but they don't care. They walk straight into malls and hardware stores, not stopping for a temp check, signing in, and wearing no mask. Thai staff are reluctant to confront them. I followed one guy in, English, asked him why he wasn't wearing a mask, replied "it's at home". He was accompanied by a Thai girl. 99% of Thai customers and staff are masked. Hats off to their discipline and following their rules.
