Actually with regards to the AC's donation request, I was always told that it goes up by 10 as it progresses. So BS will only really be 90 TL/N/NR/BS with the door fee but then those are the not so hot MPAs. In fact, one of the MPA told me that the rules are so strict that we can report this to the owner.
I had a session once with Samantha who I believe now works at Blue Pearl requested a donation of 120. I figured this is almost like a standard so I never really bothered complaining. All in all, this place is not that bad. Now with all the fresh faces, I am even thinking of a trip out of my way just to pay a visit.
