I haven't given one so far, but I see many ladies require them now.  

The deposit protects the provider from having an unused slot of time which otherwise she could have filled.  In the case of a traveling provider, it provides coverage for her hard costs of airfare, hotel, etc.

the deposit makes sure you commit to see her. If you cancel, it is understood you're losing your deposit

I guess that all the ladies are working 24/7/365 here?  No..no they're not.  Why make some ridiculous excuse for them (are you being a WK now) to simply steal a patron's money?

Based on my OP I certainly don't understand that.

Most don't.  I've never paid 1.  Never will.  No need.

While there have been some escorts I'd like to see who requests deposits, way to many out there who don't.  

At the risk of letting the cat out of the bag, I've seen some ladies who posted deposit requirements and then never asked for it or let it slide. Maybe it's a way to cut down on the volume of appointment requests to those who are committed to  meeting?

Totally agree.  I had a bad experience with a well reviewed provider who requires deposit.  I was stupid enough that ended pay the full service fee in advance at her request.  Later on I changed my mind, through our communication, I felt this lady was not honest full of lies.  I decided to cancel the appointment because I had no more motivation to see her.  I asked her to return part of my deposit and received no more response from her.  I lost $700, althouth it's not a big deal to me, but I learned the lesson. I was so stupid.  I will never see a woman who requires deposit.  Never!

I only make appoint requests to women I have a sincere desire to meet up with, but the moment I see a deposit demand (request) they immediately go onto my "must miss" list and I see no reason to even contact them.

I think this issue really comes down to clarity.  If a provider asks for a deposit on an advance booking, the onus is on her to fully express what the deposit is for and what should happen in the event of a cancellation. In many cases, the deposit not only allows you to hold your appointment but becomes a cancellation fee in the even that you should cancel with short notice.  As Mr. Fisher already explained, "The deposit protects the provider from having an unused slot of time which otherwise she could have filled".  

Yes, more and more ladies are requiring deposits to book with them for a number of reasons. Timewasters, fantasy bookers, flakes, cost of traveling expense and possible hotel expense are just a few of the reasons behind them asking or requiring.

...but a "deposit requirement" won't dissuade me from booking if I really want to see her. So far I haven't been disappointed.

I partially agree with you.  For my bad experience, I gave that lady 4 days in advance to cancel my appointment, and I only request to return part of my money and willing to compensate her for my cancellation, she didnt return a penny and kept all $700.  There are some bad girls out there.  Lesson learned. Paying deposit doesn`t deserve the risk. I will never make the same stupid mistake again.  

but it's your money, play with it as you wish.

Never. And if they required one then move on. Too many great providers that don't require them. Nobody is that good.  
Same with cancellation fees. Life happens. And even with the best intentions, especially around this stuff you have to cancel.  
And they want you to send them the $$$ or else. Not happening.

You have recourse with a credit card. And a lot more leeway on the cancellation times. 😃

If you book a room with a hotel and they ask you for a deposit, but then have no room for you when the date arrives, you have protection through your CC company. You simply call Am EX tell them what happened and usually you have your money back in minutes even if the hotel lies and tries to steal your money.

through with a deposit. We move on to the next potential client. No one likes their time wasted let alone if they've had to reserve a room or travel and this helps prevent that thus why you see more and more requiring them and will see more as the months and years roll by. As well, if they've done their research they may not easily find exactly what their looking for with "just any other provider". Personally, I offer an array of sessions and options many other providers do not offer and if a client is just looking for a basic session or a quick release I definitely wouldn't be the provider for them and I'm sure others feel the same. If that is what a client seeks yes there are plenty that will let you go on over and visit with them with no more than a first name and phone number.

At least not as far as I understood it.  We aren't talking about putting a deposit down and then having the provider cancel on you at the last minute.  We're talking about putting a deposit down and then YOU canceling on the PROVIDER at the last minute

to come to your city, then the deposit is the only protection they have against a financial disaster.

At least in most cases. Now if she cancels that is a whole different ball of yarn and you would indeed be entitled to in back in that case. The whole point of a deposit hold a time for you and compensate the lady for not being able to sell that time should you cancel. The whole point is to protect her from you canceling.

a deposit and dont refund it are the same ones who would not compensate you for YOUR costs if SHE cancelled.

Depends on what polices they adhere to.
Stick to reputable providers.
Good luck.

I would think the deposit is for holding the spot open (no pun intended) for you.  If you don't show, then you lose the deposit.  Not a hard concept to grasp.

I totally agree with you.  She should state her policy or let me know before.  The truth is that she has no such a policy listed.  She kept changing her mind and ask for more money.  She even can not meet for our scheduled appointment because she said her car broke and need more money, and had to reschedule.  That's why I lost the interest to see her.  I was so stupid and trust her at the begining.  There are bad providers there. Lesson learned.

You might be only looking at it from the provider POV, but the rest of us are also looking at it from the client POV, and from the client POV sending a deposit is a VERY dumb thing to do. Except when asking a woman to either block out a large amount of time or asking her to shell out hard money in advance of the appointment. Things like asking a woman to jump on a plane, make a special reservation at a hotel just for him, things like that would naturally require some money up front unless there was a lot of trust between the two.
