Agree with David's description of the set up. I've been to a few in West Brom and have enjoyed the whole experience, pretty good VFM. There are a core group of regular girls of which one was Ava, as discussed. Emma (of Yummy Emma fame/notoriety) seems to be very popular at the moment, wonder if that's caused an issue with Ava? I've always found the girls used to be enthusiastic and approachable, and that does include a few civvy swingers as well.
In terms of location, BS15 is in the same area as Bjanee's venue, which would make sense if you've been there. Hope to find out this week!!
