Depends on how long the session is for to be honest.
As a rule, I try to avoid SPs that have "restrictions" like this one as there are usually other "hidden restrictions".
End of the day, I just want a relaxed enjoyable session. Appreciate SPs deal with all sorts and have to be strict with stuff but it cuts both ways.
I remember an incident where the SP had a one pop policy. She didn't say it on her profile and I had booked for 90 minutes. After the pop about 40 mins in, she got up and said, that's it and offered me a shower.
I was like, really? Had a shower, came out and got the kindle out and read it till my time slot was over.
Not long after that, I found UKP. Was one of the "courtesans" as well.
