While on my last visit to TJ, before I returned to the US I visited HKTJ to find some company with the morning (8am) shift.
About 6-10 BGs arrived and a few interested me but I wanted to wait a little before deciding who to invite for a ficha (and maybe arriba).
A cute BG (a solid 6, maybe 7) approached my booth introduced herself and asked if we could talk, usually I like to approach the BG and invite her for a ficha, so I surprised myself that I decided not to send her away.
I enjoyed her conversation, she was open, sincere, and funny, though she was shy (eventually she put one leg on my lap) I thought that was probably just in the bar.
While we were talking a gorgeous BG (solid 8, borderline 9) walks by smiling at me, intriguing Little Cristobal to the point where I was about to send the first BG away.
But I did not send her away, I bought her another ficha invited her to my room and she proved me right, she was a great time arriba, reaffirming I was glad not to listen to little Cristobal.
We exchanged numbers and I look forward to seeing her again.
Though I can not be sure (yet), in this case 6 was greater than 9.


In general, I've found I've had better experiences with BG's who don't have GPS. And those are usually the 6/7's. The 9's don't think they have to work at it. The 9 I took arriba a few years ago was no fun, But i've had plenty of fun with the 7's I've gone with.
I'm not surprised by your story at all.
