As a general rule, it's a bad idea to mention any sexual service until you've meet her, but asking for a service level described on her site should be fine.  As for the feet thing, that should be no big deal but every gal is different.  Odds are she may just be busy and will get back to you.  In the meantime, do some research on fallbacks.  If you don't hear anything from her by late today, make other inquiries.  But do not finalize another booking until tomorrow.  Double booking is a big no-no.  But you do have the right to bail if you don't hear from her by the day you'd requested.  After all, she didn't confirm so at this point it sounds like there's no date.

Gosh. That kind of sounds like me. I hope it isnt.
Sometimes providers get sick or busy or personal life.
i sometimes recieve so many emails and I do my best to keep track of everything I am doing- who contacted me, who i have screened, who hasnt been screened, their provider references ect. I do not have an assitant.
What I am trying to say is sometimes providers get caught up in and an email may get lost in the mix.
You should send her email and remind her and ask her if you did anything to offend her.

If you ask me if I am pse.. or anything of that nature I will not answer those questions until I have met you. Once we meet feel free to ask. Outfit request and the feet thing is okay to ask. A good rule of thumb is to bring extra in addition to your donation just in case what you asking requires more of a donation
