I've seen them out on the street (No, I do NOT go to the Russian-themed clubs here, TRUST ME on that one) and the girls AREN'T very young, that's why I wonder. Even the better looking ones here average about 35 years old I would guess (their clientele is often older).
But your point is well-taken.
That's pretty dang sad, isn't it? Wow, mid-30s and on the streets of South Korea. Regardless of what "training" they've been to or not been to, I'd hazard a guess and say they'd sell anyone out for any amount of money.
