I've.seen a thai woman crap in the gutter and thai men piss on phone boxes and walls in cties. Nobody bats an eyelid.
Most taxi riders piss on the street nearby.
Give me the location of 1 public toilet in phuket, pattaya or bangkok that is free and provided to the people by the council and not a truck stop, shop or bar.
I can think of 1 in a park. Rarer than hens teeth.
