Once I know a KTV girl in Beijing who didn't agree to follow me back the first time. After dating her out for a few times (note, still paid her tip), she went back with me one eveing. When I offered her more than normal tip, she refused and was in fact quite upset. Saying she didn't do this for money. At that time, I was quite ashamed of myself.

Then, with a couple more outings (tip still applied), she said she needed a computer and asked me to sponsor her 6,000RMB.

You draw your own conclusion. For me, it is very clear now that KTV girls are there to make money.
