Further update:
Just had an email from the SP in question on AW asking if i'd be interested seeing her again tomorrow in the Hotel.
I checked out her revised profile on AW and it make no mention of her "owner" being there. So contacted her back and asked if she is now working independently. It seems that she has booked a room with a lounge area that he will be in whilst you engage with her in the bedroom.
I think people need to be aware of this as i think potential clients need to be in full possession of the facts before making any booking.
Some may find it off putting that a guy is in close proximity listening in "for safety reasons".
Forewarned is forearmed.
