Indeed they are, never in my life did I think I would be reading a sign in a 7/11 saying the sale of marijuana was prohibited to under aged and pregnant women !!
I had a scoot run into the back of my stationary pickup (Traffic congestion)... Damage to the rear was fairly decent and the cab rear window smashed when the scoot rider came through.
Scoot was demolished and rider suffered many broken bones.
Not sure to be honest, all came with their farang wives and I dare not ask their ages.
1 fella has a Thai lady who he met after his wife was killed a few years ago, I think the Thai lady is about his age.
I do not but using your "theory"... should each individual Thai IO be fluent in the language of all visitors to Thailand.... is that also part of the employment conditions ?
