Hope it won't happen..lol...Happened to a friend years ago...Doubt it if they are still doing it...
Friend had to give her an Gold AE, over 30 years ago...Well, she only charged about 3K USD/month for next 10 years. Stupid friend.. Escort fee was only $80 USD/24 hrs.
Also, the Korean G gave a gold necklace to my other friend at the airport and cried. Friend took it and never never kept in touch with her..
I had Korean girls here, but Po Po Ching...lol...no trouble.
