From what I'm told it varies. Depending on wwhether they come in w/ a warrant or bust based on an act that happned during the visit. The phone girl is almost always busted. The cops often arbritrarily pick the working girls,who are there but not in flagrante delicto. Johns are rarely busted,but hassled (eg give me ID.... What would your wife say if I called her) in order to gain incriminating evidence.
