Like every provider, go in there, tell her what you want and see if she agrees to your request.
If she says Yes, then stay. If she says No, then leave.
90% of the time, MPAs I visit provide me with FS. Because I ask them for it. You have to ask them or they won't do it. Girls don't like sex for sex. They like sex for money. So, you have to let them know that you need FS or you won't stay. Be polite about it, of course. Don't put someone in a corner or they will refuse because you made them feel disrespected.
