Ladies, come out come out wherever you are...I think I'm gonna need you here.
I see by today's increase in rates that this got me thinking, I wonder what are, if any are the basic grandfather rules. I know it would be on a case by case basis but in general, what might those rules be? Girls do you even offer them, or is it a "hush, hush, wink, wink" thing?  Or is it the "I won't tell if you don't"
Guys do you even ask, even if you haven't seen her in a year or two?Now me? I have never asked, her rate is her rate and that just the way it is. But I have a story to tell.......Suck it up, it ain't that bad.
Met this young lady (we'll call her Ms. X) about 7 years ago. I enjoyed her company and subsequently saw her 3 more times over a 4 month period. Oh, she was $5XX then and our dates were of the 2 hours. Then in time, her rates ballooned to 6,7, then 8XX. I moved on and she became like the flavor of the month in Vegas. Then about 2 years or so, I met a friend  (We'll call her Ms.J) for drinks, nothing more. She bought a friend along, who happened to be Ms.X. We then decide to have a lite dinner,all of us. As we're talking Ms X asked me why we haven't gotten together, why I never called her. Told her flat out that I couldn't afford the price of admission now at1K. She laugh and said, "Don't worry, I'll see you on our old pricing".
So fast forward, on my next trip, about a month after our lil dinner,  I reached out to Ms.X, I mean the old price for this beauty, shit why not??
Cut to the chase.....never heard back. So much for that.
So back to the grandfathering...what's the deal?

a way for providers to fill holes in their schedule with a known commodity.  Since you are paying less, you will go to the bottom of the list.  

hard and fast rule for everyone. Once again, this is a case by case depending on the provider and their business practices. There are providers who do *not* honor grandfathering what-so-ever, there are some that do with parameters (i.e. only grandfathered if you've seen the provider 2 to 3 times within a calendar year).  

she probably only said she'd see you at the old rate to try to cut out the other lady if you saw her later on that night. Or else she would have saw you at the old rate when you inquired afterwards instead of ghosting you.  

0.P.?
Recall the quantity of alcohol consumed during your "reunion dinner" with Ms. X?
The answer may explain why you never heard a peep from her when you finally
reached out!

Like Ms. Savage says it can vary from provider to provider.  However, I would assume on some level it has to exist because old business is just as important if not more important than new business.  You definitely need regulars to have an established book of business but it is just as important for you to grow as well.

There is a pecking (or pecker? - Lol) order with every provider.  Top priority goes to guys who do weekends, FMTY, and overnights.  Next is guys who book multiple hours.  Next is the one hour Johns.  Lastly, is the one-hour Johns who are grandfathered in at lower rates.  As Laroche says, they are happy to fill holes in their schedule with guys that are paying less, but when they have plenty of bookings by higher priority customers, there is no need to do that.  

We raised our rates once in 13 years from $400 per hour to $500 per hour in October of 2016. No one was grandfathered in and no one complained. We got a few inquiries about grandfathering and that was about it. I don't foresee another rate increase in the near future as of now.

Certainly as others have said there are no rules. It's up to the individual lady. Some also set a time limit on grandfathering, i.e. you continue to pay the old rate for 6 months then the grandfathering ends.

of how the agency needs to be run..  

First of all hpygolky,  
  some of the prices on this site might just right out crazy!!! But then again so are some of the hobbyists who try to be as cheap as hell. I have have a few hobbyists who thought that he should pay whatever he felt that the service is worth. LMFAO!!! let me get one thing straight. The Hobbyists who are trying to take control of the Providers (Like when she's available, What she charges & Etc.). Those Hobbyists must be crazy and as far as the prices are concerned......
Have you thought about the fact that the Provider has more at stake then you "The Hobbyists" do?! We "The Provider" could  go to jail for days or months, Have a soliciting of prostitution on our record (Regardless how secure this site is or might be).  We "The Providers" always have to jump through more loops then the so called "HOBBYISTS".  So therefore,  before you "The Hobbyist" starts bringing up things like prices, How the provider just laid there lifeless and what not.........Think how we have to deal with the ignorance of men who are so cheap ass well as being judgemental & etc. If it wasn't for the so called HOBBYISTS hitting on us for whatever reason that they have then we "Providers" would never be charging what we are. I have been doing this for almost 30 years (Since I was eighteen and half). This is just fruit for thought. Respect goes both ways.

Thank you.

"Have you thought about the fact that the Provider has more at stake then you "The Hobbyists" do?! We "The Provider" could  go to jail for days or months, Have a soliciting of prostitution on our record (Regardless how secure this site is or might be)."

That's exactly why the offer was extended at that time and place. It seemed (I didn't know it at that time) that there was some "gamesmanship" going on between the two young ladies. A bit of a competition (It's Vegas).
Long story short, I saw someone else that evening. Then Ms.J calls me at 2:30am to tell me why Ms.X made the offer. Ms J met me for a late night drink and to have a laugh over what happened, then we went to my room and......had a great time.
But I did eventually reach out to Ms X about that that "offer"...never to hear from her again

Angling for a discount lol

Lets face it mis. Newbie 21 years old will get lot more than the 52 year grandma who 300lbs and you need several mask.   From what see there a 5% a year on average compound depreciation over of woman sexiness V's experience. If we go into high inflation the price will go up.

Over a good number of years my wife raised her rates from the 200-225 to about 500 average.  She didn't really grandfather clients, but did for the first visit after a raise give them the old rate one time.

Seriously, why don't you learn how to write English?

It actually more time to write like this than playing it straight.  I have tried in the past to write like someone who is an ESL student, and its a lot of work to get it right for someone who speaks perfect English.  

From personal experience, your wife did grandfather my rates as long as the contributed to her "3 hole experience".

lol, ahhhh you must have been somewhere in Europe also....

There seems to be an awful lot of discussion here for such a simply put question...
Let me simplify this:
Providers are working for the purpose of earning a living. So imagine that, in your occupation, you have the ability to schedule your own appointments based on your own criteria... The most money, earned the fastest... that comes first, right? Lower amounts move on down the list respectively.
Don't get me wrong, even as professionals, providers do occasionally play favorites. But overall, money trumps familiarity or favor every time.
😘

First off let me say  I completely agree that this is a BUSINESS for the ladies and they have the right to grandfather rates or not to at their own discretion, and to prioritize bookings by any metric they choose, just like any other business does.

As anyone successful in business that sells many "units" of product must learn, those who charge the highest price are not always those who make the most revenue, or profit.  There is a  trade off between price and units sold over time that should constantly be reviewed and adjusted, based on the strategic objectives of the company.  Add to that the need for "production" guidelines (like number of units that can be produced for a certain cost, required margins for COGS, etc.) and pricing strategies can get complicated. But they are critical to the success of the business.  

Regarding the last paragraph and alternate pricing strategy.  Then the gal should at least provide a results chart of her activates to include number of dicks serviced and in which size range so that the potential client can gauge if she might be a fit for him.
a. Percent of cocks 0.05 to 5.9 inches serviced.
b. Percent of cocks 6.0 to 9.0 inches serviced.
c. Percent of cocks over 9.0 inches serviced.
She of course, should indicate her preferences so that she and a potential shopper do not have to waste time in exploring  whether a good match is possible.  

The "pecking order," as you phrased it, is entirely up to the provider. I offer the rates a patron sees me at in perpetuity as long as they consider to see me regularly. I'm also clear that regularly means at least once every 2 months. Over 90% of my business is repeat 3 hour dates, with a mix of true regulars (once a month or once every 2 months) and those who see me close to quarterly (3-4 times a year). It would be very foolish short term thinking of me to de-prioritize my devoted grandfathered patrons in favor of someone who sees me once, or once in a great while, for a travel date.  
When I devote myself to those who devote themselves to me:
-I make far more money long term
-incur far less risk, business feast/famine, and resulting emotional drain

might be a good idea, but few mongers who got the lowest price would admit it in their review.  LOL

Very true..... lol

I don't think there's a Grandfather Rule for this particular thing. I've been doing this since i was eighteen & a half (I'll be 46in February) and never heard of a Grandfather Rule (Can someone educate me on that subject?).  

One definition  
If client is old enough to be your grandfather he gets a 50% reduction in rate /
Another ten % if he can get it up long enough for you to be honestly  satisfied.🤭

I think her grandfather would have to be upper 80's or 90's.  Definitely should get a senior discount.

My wife, who was a provider as mentioned on here before, had pretty much the same views and practices.

I would be pretty upset if my employer told me that my compensation was “grandfathered” for next year and I wasn’t even going to get a cost of living increase.  Inflation has (almost) always been a reality.
