I tend to do the opposite, especially when she's newer to the Sugar Bowl. Of course, it all depends on her primary reason for sugaring. If she's looking for basic needs like help with rent and car payments, I will have her walk me through her monthly expenses and then craft an offer based on seeing me x times a month to cover y percent of her bills.
If she is generally financially secure and wants to upscale her lifestyle (better clothes & jewelry, saving for a new phone or car, exotic vacations, or just be taken to high-end places), she will have a number in mind, and I will try to get her to reveal it to me. And again, I will craft an offer based on seeing me x times a month to cover y percent of her target.
Neither of these will convince a GPS Princess to come down from her $1k PPM or $10k target. The sooner I can verify that she's in that range, the sooner I can wish her luck and move on. As I'm sure you know, netnoy, never chase GPS asks. She will lead you over a cliff and you will land squarely in Simp Land.
Ultimately, as I have said in the past:
She has the power to say "yes."
You have the power to say "no."
Use your power for good.
Life is good
