Hi Tiny,
The girl I mentioned is Sammi, she used to work at Bluemoon, not for too long, only a few months but she was taking the forum by storm and we all love her company for one reason or another!!
She has since returned back to HongKong and retired from working but may return in the near future as a mamasan, if you like some advice or something, you can try send her a PM (private message) and hook up.
I think your friend is giving you some good advice and if you are interested in working in the outcall industry, this forum is a good place to do some research, the After report section is particularly good for seeing how the WL provides the various services and most importantly the difference between good and bad service!
Just my two cents
Good night
