Any parlour you go to will either have a door fee and the girl keeps all of the fee in the room, or you pay a flat rate and the girls pay the door fee from your fee. In Northampton we have Soft Touch which uses the first system and Massage Northampton that uses the 2nd. The parlour must take a cut somehow.
In the first system it is transparent the split of the fee. For example at Soft Touch a 30 min meet is £25 to the house and £45 to the girl. At Massage Northampton a 30 min meet is £60, which I have been told is split £20 to the house and £40 to the girl.
The split at DL seems very fair to the girls assuming they keep all of the £70 fee.
Aurora's aw profile looks very tempting and PSE with Domination, Filming , OWO, Facial, Toys, WS all listed at £90. However it seems she doesn't work off that profile and prefers to work at DL. It is doubtful you get many, if any, of those services at £82.
