You can get P4P almost anywhere in Thailand. The Thai scene is huge, way bigger than the tiny foreigner-oriented zones.
I've seen it myself maybe three or four times, including once with a Thai guy whose wife had just given birth.
He called up a couple of youngish girls he had on speed dial, picked them up and took us to a love motel a bit out of town.
I chose to sit it out so I just waited in the car with a very sad looking girl who looked like she wanted to be anywhere else.
Much, much seedier than the "Pattaya style bars" that you decry.
Dude was a car battery salesman, so just an ordinary guy. The kind that you "Pattaya bad, real Thailand good" types think are the "salt of the earth". You probably wai them every day ????
So yeah, unless you live in the jungle mints from anywhere then you probably DO live in a "flesh pit" but you're too blind to see it.
