Varies from provider to provider...

There have ben threads on this topic before. Most will say tips are not expected but they are greatly appreciated, some opinions are they would rather have you repeat with them instead of a tip. Tips can range from any $ amount you wish to give to gifts (gift cards-jewelry-whatever) some providers even list gifts they prefer on their sites.

From a CLIENT perspective there are those who tip everytime-just sometime-if provider went above and beyond- or may tip just because they don't plan on seeing her again.

On the down side, if you run into a provider that asks (or demands) a tip up front before anything has even happened, then you definatelly made a bad decision when you arranged to spend time with her. That's probably the only thing everyone will agree on when it comes to  discussing "tips"

but always appreciated. However an indy lady will never feel like a waitress would about tipping and hold it against you because you didn't tip. We set our rates at a comfortable price for ourselves and that's all there is to it. Should you want to show an additional sign of appreciation? Book again with her!

I also feel very touched when a gentleman brings flowers or chocolate but some ladies may not care much for that. It's a personal thing. Once a man had really listen to our conversation and picked on the fact that I wanted to buy a particular book and sent it to me the day after at my hotel. I know it's simple but it's something I will never forget.

the best tip is a repeat session.

I specify GFE appointments which are normally all inclusive.
I do tip FBSM providers because very often the "extras" are not included in the up front price.  (I add up to the ammount I would expect to pay a FS provider).

My tip is usually another visit to them

Given that the average donation for a session is usually about 10x what would usually be considered a decent tip, I'd wager it's appreciated more.  If you do that, though, bringing a little token of appreciation wouldn't hurt, particularly if your previous sessions were pretty special  (but then, why else would you be seeing her again?).

there are endless answers about it.  I see only indie girls and do not tip.  But I do bring gifts, candles and a VS gift card, which are always appreciated.

When I first started hobbying I never use to tip, because I saw providers so much, that it got a little too expensive.

I now hobby once or twice a month, so I do give tips sometimes.  If it's a provider I've seen in the past ans we get along well. There have been times, where I would simply buy them lunch, and go over to speak to them for a few mins. (note) this works great becuase I've gotten really nice discounts later on.

But as far tipping I look at how the provider treated me from our first contact on the phone, to the our final hug when I'm ready to walk out the door. If she was kind, and got the job done (made me pop) I simply reach into my pocket, and pull out a 20.00 dollar bill, and say thanks for a wonderful time.

It's always unexpected, and I always she joyfullness in the provider eyes as I walk out the door. Which means I'm setting myself up an even better session next time.
