Happy 69th post Sua. ;-)
I have to agree that some of you pay way too much for your tips. Standard service should get a standard tip. And don't be afraid to tell mamasan or papasan that you were not happy. It's a business and it's YOUR MONEY. Tell them that you won't come back if the services is bad.
Now maybe some of you just write bad reviews. Did she do something worth the extra tip? If so you are not telling us. So put it in the review. And also be smart and tell the girl,"I am giving you extra because you did this......"
There is a girl who when she does a BJ she gets all into it. I mean sucking your boys, tossing salad, everything. She was worth the extra tip and I always reminder her why I liked going to her. I also would share bad experiences. This was so she knew what I liked and what I didn't like. Also I would tell mamasan that I liked that girl too. I can tell you that I knew a few mamasans who would get rid of bad girls. It effects their bottom line to keep bad girls around. And the ones that appreciate your comments invite you to come back and do things to get you back. We'll talk about those another day.
Lastly please try to respect the area you are visiting. What I mean is if you are in Chicago you tip $30 for a HJ in other areas it might be $40. And yes while some white providers want $50 or more make sure that they are giving you great service before you hand that tip over. Otherwise $30-40 is fine. And if she asks for more then tell her what's up and what you expect.
Think of it this way. You are not going to impress her with your money. You are just another guy getting a tug. But you can school her in what you want and don't want. Then she can really earn what she wants.
This has worked for me.
