I did get a rise out of one woman. I asked her if her father knew what she did to get money. And she said "F*ck you". or some mispronunciation of the obvious well known phrase. (It's amazing that after only 2 months,I can no longer remembe exactly what she said. )
I ask women if their father knows what they do, and men if their mothers know. I know that some of these girls don't feel close to their fathers, maybe were even abused by them, but I think most girls even in the countries these people call from aren't in that situation, and they want the respect of their fathers. I'll admit, if I were broke and needed money to eat. I'd take a job like this too, and even worse.
I don't use the phrase, "earn a living". I just say "get money".
