I'd love to tell her to her face that her service was crap but that could be dangerous, best to pocket her tip and get out of there quickly and never go back, even if its a different escort in that same apartment.
You could write a negative review but that will likely be taken down or modified to make no sense.
I have been tempted to leave a note in the lift to warn the next victim but unfortunately its not just clients and escorts using the lifts.
To anyone that doesn't like me here.
I hope you need to pee 3 times tonight, but that you only wake up twice.
