I've only heard this happen maybe once in the hobby and it ended up being a horrible time. The provider ordered before the session and the entire time the client smelled fish from her breath and puss. Horrible fucking time. LOL
This decision is more of how you feel. I mean you could say yes but does that mean you're paying an extra hour for her time including the food or is this time not included. Thins go through your mind that you aren't ready for, so as a newbie in this I think you did the right thing. As time goes along you could get a little more comfortable with something like this.
Myself though, depending on the provider, I would have said yes. It's a nice way to have them remember you and it's great to have this added in s a way of investing. This is just me.
