Sure, back in the days of sex magazines and the yellow pages (gasp), there was plenty of up-selling.  Many times the rate was to get them in the door and if you wanted them to actually perform a service it cost hundreds extra.  

But TER makes it simple and takes all the guess work out of what to expect.  If you are worried about paying more money for additional basic services once you are inside the room, then only see well reviewed ladies. You'll know exactly what to expect per their hourly donation.  The reviews will tell you the services you are most likely to receive. She is not going to stop in the middle of the session and demand more money.    

If you are running into ladies who are trying to extract (some may say extort) extra money from you for basic run of the mill GFE services, you are seeing the wrong women.

I can only speak for myself

Only time I have ever added an xtra it's a travel fee but I state the fact before we meet so there is no issue. Secure emailing systems exist so that those kinds of conversations can exist.  
I'm sure though that these women have their reasons. Not everyone has access or knows about secure ways of talking about more sensitive topics.

you are both right  and ive seen some great women over the yrs thanks to ter  
 ive been going thru reviews and i just started checking out the boards, which has really opened up an opportunity to meet  some great women i wouldnt have known of  
I was seeing the same provider for more than a  yr im pretty faithful when i find some one and we get along well unfortunatly she went back home and now im looking for another and just in the last couple of weeks ive run into this problem twice and one of those providers was totally my type i was going to daty and she stops me and says thats xtra  the last time i checked thats part of gfe but what ever.   im from brooklyn maybe its a brooklyn thing but do to my work (restaurant) dont get off till after 10pm and alot of well reviewed providers dont see clients that late espesally new ones which i get.
what im really trying to say as a provider wouldnt you want steady regulars opposed to new guys every day?
in my business you gotta keep them coming back  
nickle and dimeing is not the way to go

I am based in a country where we can have full lists of services our on website which makes things so much easier  

Escorts have always been paid for their time - 2 consenting adults doing as they wish  

In my opinion things that require preparation time like Greek, clean up (watersports) or extra costs to the lady (strap-on apparatus, etc) should be extra's and mentioned before the meeting begins.  

GFE things like Kissing or OWO a girl is either comfortable doing them or not and it's so much easier to have everything in 1 base rate

We have a disclaimer on our site underneath the services list saying that services can be refused to cover hygiene issues

If you've ever worked in sales, upsells are pretty standard procedure. Whether or not it's ethical is another matter. A sort of upsell is even ingrained in our health care system where we are often charged separately for things that could be clumped into a single charge, just to generate additional revenue. So in other words, an upsell is very common.

However, as an escort, I am technically not selling anything. Rather, I am getting paid for my time. So I'd say, in the escorting world, especially here on TER, I would think an upsell is against the unwritten code of conduct.

First and foremost, the main priority for both parties (besides safety, being respectful, those types of things) should be to create a comfortable environment. Especially for a gfe, it shouldn't feel so "transaction-y" and awkward. So I definitely agree- bad way to conduct business. Having said that, as someone who provides GFE, there's several things I won't do. Even if it's part of the gfe, if there's health concerns or something like that, it's normal to decline and that should be respected by the client. But again, saying "sorry I don't really like that" and "that costs extra" are two COMPLETELY different things.
Last point I want to make is to be aware of the providers you're choosing - cost wise. Just like with any other thing, you get what you pay for. Now I'm not sure if this applies to you since I don't know what price range you're looking at.. But usually when the business's objective is just to get you through the door and then upsell, upsell, upsell, and nickel and dime you, they're more concerned with trying to get as much money as possible in that one transaction instead of providing quality service (this also means charging more because you know you're providing quality) and hoping that leads to loyalty and keeps the customers coming back. That's where quality vs quantity comes into play.

you get what you give

sometimes i feel like I'm the only one giving and giving.... i have regulars who want to pay less for the same service even if I'm not giving less. so for someone new i want to make sure they are generous from the beginning because i don't like people coming back if their intention is to walk all over me

I don't want to see someone who upcharges for kissing, BBBJ, DATY or what I consider to be the basics.

However, if I am not interested in Greek, for example, then I don't mind paying less than someone who wants that service.

Really, I just don't want to be surprised.  A woman can set her fees however she likes.  As long as I know, before I get there, what it's going to cost me, I am fine with it.

Agreed that those kinds of things are a mood killer.  

Reviews are helpful in terms of establishing expectations for what should be available to you when booking a session of any type (GFE or PSE or anything else)  

I think upselling is tacky and a logistical nuisance; it also still requires a "discussion of the donation" so doesn't seem logical in terms of how to handle things.

..to thoroughly research the companions you'd like to visit. Personally, I don't maneuver in that way as I also think it derails the mood. At the same time, I don't think there is anything inherently wrong with upselling. Though from what I've seen, more reputable escorts will clearly convey the different levels of experiences they provide so a potential guest can be well aware ahead of time as opposed to being subjected to that awkward surprise factor.

Some would not think that there is anything wrong with extras. Like I mentioned, upsells are commonplace in all businesses.  

One thing I forgot to mention is, in environments where prostitution is legal, there may be a base rate and then everything else is an up-charge. I'm mostly referring to what I've heard and read about working in Australia. In the parlors there, there is usually a base rate of say, $200-400 for the hour depending on the caliber of the place, of which the lady gets half. All the extras are considered tips and the lady gets to keep it in the entirety.  With the upsells, the hourly rates can still be 300-500 an hour in a legal, safe environment with a good supply of clients.  

With escorting, one is technically charging for one's time. I think this is true about the 'escort' term anywhere regardless of the legal climate pertaining to sex work. What may occur during that time may be listed in the ads or reviews but is not technically, contracted for, whereas the time is. What happens within that time is at the discretion of consenting adults. Of course, in the US, the two consenting parties can still be prosecuted for engaging in what grown-ups do because historically, our government  likes to misappropriate valuable monetary resources to police it's citizens' agency over their bodies, as was the case in Texas vs. Lawrence, along with a few other examples I'm undoubtedly leaving out.  

Someone who upsells is obviously not charging for time, and is therefore, not an escort in the truest sense. Also, that sort of behavior doesn't really conform to the expectations of TER. Even though the guys here (especially as of late) ask for some pretty explicit stuff, the site is structured to reveal hourly rates with reviews written to suggest activities with which an escort may be comfortable in private, not services or expectations.  

At least, that's my three cents...

This is usually for when somebody wants unusual things that I need to prep for or brace myself for.  

Charging by the act or a hybrid of time and act is pretty low rent.  Just charge a comfortable rate and treat it like a casual date with a gentleman, rather than a menu for a cheap, fat bastard at the drive-through window to pick from.  

Plain and simple up selling is a bad idea. After over 15 years in this industry I know that being straight up with a price and making it all inclusive just makes for a better reputation and experience. At the end of the day you are paying for a great experience and up selling is a buzz kill.  

As a female, when I get going I don't want to stop and talk about extras for this and that. I just want to have fun period. But maybe that is just me. LOL.
