Thanks for all the responses. The informaiton about the 141 website has been very helpful.
As for staying in touch with WG's, I should have mentioned that I live in the States and probably won't be back in HK for many, many years. Hence, the e-mail rather than phone numbers. The way I see it, I had a good time chatting with these girls and I'll almost certainly never see them again, so it doesn't hurt to try to keep in contact. Obviously, I didn't give them my personal information, but I wouldn't mind chatting about life or even helping them out if they made it accross the Pacific.
Anyway, I know one of the girls was after my citizenship. She mentioned wanting to go to the States and hinted that I should take her back with me. I kept dodging and told her that if she gave me her contact info, I'd hook her up with one of my well-off US friends (who is hopeless with women, so win-win in my opinion). To this, she just came straight out and blind sided me with "Why not you and I get together?" I forgot how I got myself out of that one... but to her, I must have looked like prime meat. She was probably late 20's and dying to get out of the business/country. I am early/mid 20's, ABC with vacation money to spend, and decent looking enough that I'm pretty sure I could have picked her up if I had met her at a club. While her persistance put me on guard, she was cute and I had a great time talking to her (when she wasn't propositioning me). Service was amazing too
She gave me an e-mail address and a phone number that she said she'd keep even after she stopped working.
Now, the other girl was something completely different. She either had GFE down to an art or she geniunely liked me. I think somewhere between my age, struggling chinese, and inexperience with 141's, she decided that I was just hilarious. She was cheesing the entire time and was more interested in joking around me than rushing me out even though the hallways outside were full of people. She was great fun to talk to and I wish I could have had a chance to take her out to dinner just for the company. While she did say that she worked all the time, she also promised that she'd contact me... I just hope she hasn't forgotten.
One thing that struck me about all the WG's I met was that they all seemed very sincere. While I know that their job is a means to an end, they always seem so cheery and chatty. I suppose it's part of the job to always seem like they're having a good time, but I felt like I had more fun chatting with them than getting down to business.
