I like to have a great time with a provider enjoying some good chitchat.  
One may bring a bottle of wine or some fruit to spice the section a bit with the provider.  
The question is, beyond wine or chocolates what other things would also be ideal?

Check their webpage, usually there is a list

A good tip should be enough

Many ladies will appreciate anything- because the thought is what counts. However, gift cards are always a fabulous option. If you don't know her taste, you can go with something generic like amazon. If you know where she likes to shop, you can be more specific. It's always a very nice gesture.

Thank you all!

The best gift I can get is a donation to the charity I have mentioned on my website. I have received other lovely gifts as well perfume, lingerie, etc. But nothing makes me happier then when I check my charity email and see that someone has donated. I also offer an extended date for those gentlemen that give from their heart.

then you probably have an idea of what she likes or are comfortable enough to ask and get pointed in the right direction. If this is the first time you are meeting I would suggest anything you bring be store sealed. Meaning If I don't know a client and he brings homemade cookies… they are going into the rubbish. I know it sucks and hurts me deeply as a certified cookie monster but…trust is built over time. Bring cookies, fruit, wine-but make sure it's sealed.

I second Missy.

A great appointment, considerate treatment, and an honest review. That's all I expect.

All of you gave important ideas and opinions!
