I'll give you a little credit.  Not all your posts are clueless.  But this one?   R you shitting me?  I guess that's what you happen when you roll with BP girls.
Your thoughts, oh never mind!

sometimes its not clear

either their site is vague or they have a la carte pricing which I REALLY hate. Except for greek which I understand.

Like, "a couple of hours"...do you mean two, or eight? And if they don't mention time at all, I always get nervous that they'll string me along and then make an offer for a half hour (Eros guys...ick).  

Makes it so much easier when guys just say something like, "Hi, are you available Friday afternoon between 5 and 9? I was thinking to do a dinner date or possibly the 6-hour [insert what it's called on your site here]"

When a guy is REALLY vague about how much time he wants, it usually means that he wants to PAY the least amount on my site, but have me stay longer. So I always ask, even if (especially if, sometimes...lol) it's a regular. But I'm pretty polite about it...and I'll keep the discussion confined to time rather than money.  

Makes it so much more fun on BOTH sides when we can just schedule without hassle!

I'm the *worst* about asking for/negotiating $$ so I'm usually pretty shy about peeling though the bills right in front of someone. Just kind of tacky. I'm usually one to not touch "the envelope please" until I'm on my way out the door. I think it kind of sends a message. With that said - I'm able to live by that protocol due to stringent screening. I have to have a certain level of trust beforehand to trust that someone will slip the correct fee in. If it's a first timer or someone that I've only screened through work information I usually try to find a discreet moment (alone) to glance in. If you're **really** good and have been providing for a while you know what a stack of 20's feels like in denominations of 3, 4 & 500. Sometimes someone is short a twenty but I feel like they're doing that to test me somehow. I don't like it but I'm not going to call a client over being 20.00 short either.  

It's one of those situations where it's like "you be cool and I'll be cool". : )

a gentleman who has a clue. Pay what she asks. Period.

I have never, and never will, negotiate the donation. I have already researched (read her reviews, saw her pics and know her rates) and being that I've arranged a date I've agreed to the rate for the time. However, nothing and I mean nothing will make this a one time only date quicker than upselling. If the lady wants a certain rate for a certain amount of quality time and has posted that, then that's what I donate. I don't tip either, I'm not sure if that is against protocol. I have given Birthday gifts to two of my favorites, and that equates to a tip I guess, but it was a well thought out gift based upon what I know she likes. To just lay down an extra $, no I don't do that, but I also don't bother the lady with asking for more or trying to pay less.
