You're right there Tania on mutual understanding but it's also the fact, there are WL's out there that's after the quick buck cut the session short or do under average service. It's like you getting a massage & a getting guess work massage from head to toe for 5ish mins then repeats it through out the session. Even you will be demanding money back after 10 mins.
Then you have those that cut sessions short booking 1 hr but only get 35 mins, and you're out the door. We can be absolute gems to the ladies but, when they are flipping punters like burgers at a fast food joint. Or when you're asked to fork out another 100 bucks on top but don't, and she gets pissed off at you and changes the service to bad. You can't come out still thinking positive about the experience.
It'll be great if this mutual understanding is spread and works, but in truth only punters will know of this. WLs outside this forum won't.
It is also the reason there is so many bait and switch adverts, because everyone mostly don't walk away. And always "Takes one for the team". You don't pay for 5 star service and get 1-2 stars instead. I bet there are punters out there wondering why are we are paying so much $$.
