A bird taught me how to non aggressively ask if a girl is on the game.
According to her, "Do you sideline?" is much much better than "are you freelancing or a prostitute?"
KHUN TAM SIDELINE, ROO PLOW?"
Which translates to roughly to "do you work sideline, yes or no?"
I've had 2 ex BG get pissed as I didn't ask this simple question beforehand.
