I agree with the consent comment (which significantly falls under YMMV but has a greater overall meaning), the booker/agency/etc comments (at least one agency is poor with this) and the comments in her final paragraph (which all professionals).Prior consent to sexual services cannot be given, consent is always ongoing, so I don't think that services can be "carrot dangled". Everyone should know this, it sucks if she never had the intention, but there's no way of knowing that unless several clients have it happen to them with the same provider, but just once we don't know what happened. Also given that the majority of people here go to agencies/spas, it's not the girl carrot dangling but the bookers. But I'm sure other things can be carrot dangled, that she doesn't normally take outfit requests unless it's a regular, that if you see her often she will give you extra time, or a special rate, type of thing.
The absolutely most annoying carrot that clients try to dangle is "give me a good price I will be your regular" first off, they are full of shit because they cant know that they will want to see me again before seeing me the first time... and why would I want a cheap regular???? I just offered one of my good regulars (he sends me money for xmas, my bday, valentines day, lingerie etc) my old rate for our next 12hr date and he said no, he will pay my currently rate because i deserve it. He still would be a good regular if he took the offer, but that's because I OFFERED.
I had taken previous SP centric carrot dangle comments to be in the vein of false advertising (which based on documented experiences on this site seems pervasive at least in some parts of this world - eg Leolist where contact is direct with the SP) and not in instances covered by YMMV/consent.
