• “If it were a Thai person, they’d have been arrested the moment they unzipped.”
Thai taxi drivers regularly unzip and pee at the side of the road without any consequences.
• “They must think they can do anything in Thailand. Our laws only apply to locals.”
But they don't apply to locals.
Where I live it is the Thais who drive their motorbikes in the wrong direction, on the pavement, without a helmet, while texting on their phones.
I see Thais openly breaking the law on a daily basis but I don't see any Thai netizens complaining about that.
