Jay, thanks for referencing me.
Thank you for developing a systematic approach to this. I've used it well a few times, but often times I completely forget due to anxiety and distraction when seeing the girl. I have to keep working at it, and hopefully this will become automatic every time.
I also need some better questions since I mostly do vanilla, partly to gauge the answers but also importantly to gauge their attitude. From my experience, rushing to start the session is a bad sign, as is the girl getting irritated before the session. Conversely, girls who are relaxed and don't rush to start the session have provided good service.
Maybe some vanilla questions to ask:
* Do you rush me to cum, or can I use my full time?
* Do you kick me out after I cum, or do I get the full time?
* Can I cum inside the condom inside your pussy? (There's been a few times where the girl didn't allow this, with no previous warning)
I remember in a flat one WG 'refused' to shake my hand and that turned out to be a
So a handshake test could be the 5th S, "Shake". Although I'm pretty sure some of the poor SPs initiate the hand shake at the beginning, refusal to shake hands seems like a reasonable indicator for poor service. Better than the handshake were the few occasions the girl has given me a hug and cheek kiss before the session even started, and those were all very good sessions. But that was initiated by the girl. I could try, but that might be pushing it. So I'll try the handshake to start.
