I've noticed some RNT shops requiring full payment upfront rather than the massage fee with tip being paid directly to the girl. I can see some pros and cons here.

Pros for shop
No problems with customer.
Full payment taken and customer can't argue later.
Customer cannot negotiate with ML and shop controls everything.
No opportunity for customer to make a run for it e.g. promises to ATM to get money but never returns (it does happen).

Cons for customer
ML can decide how long she can keep her clothes on and when to remove.
Customer is at the mercy of the shop and ML. If customer didn't enjoy session just bad luck.

What do guys think? Paying the massage fee to the shop and the tip to the girl is my choice. What do you prefer?
