I had a great lunch date with a very sweet man just the other day that took me to eat some wonderful Thia food and we have never seen each other BCD... So to answer the question, if I am not doing anything then yes I would love to go rather I have seen you BCD or not....
By the way to my date "THANK YOU" I had a really good time ....
To me it all depends on the provider and your connection with the provider. It is a bit of a gray area. I believe it also depends on whether the provider has a bf/husband which some do. I personally wouldn't just call them and ask them for drinks. I would possibly bring it up in passing during your next session and feel things out. I would just approach it more delicately. I wouldn't push it too much. They might think you're trying to get a freebie.
Oh geez. We pay x, they do x. Yes, they give us some extra time or something else. I was a good client of a provider. I wanted to watch. She said yes but only because I never pressed her. It was wonderful.This was great, and meant a lot based on mutual respect.
