I have had "run ins " in 2 states, and BOTH were when I was young, dumb, and worked through a service, where I was sent to the guys room, the Following. Almost Always applied :
1. No issues regarding "donation ",price was no object ...
2. They request more than one lady, and or see if you can "score " drugs for them, and will offer you some type of alcohol etc to appear "down "...All in order to compound your charge.
3. It was Always, Always, Always a situation where they ask questions about what is to transpire during the session, despite having had an operator tell them, assuredly that it was Full service, satisfaction guaranteed...then when you attempt to be obtuse or vague, or even direct about not answering, they repeat a "phrase "repeatedly,so as to alert the officers,usually in the adjoining room, that it's "silver bracelet time "for you! Despite whether or not you've actually done anything illegal at that point or not!
So, unless you are being flagrant (I.e."too much traffic "",suspicious looking characters, other odd or attention drawing behaviour), I'd have to agree with the above, that police generally fear the unknown, and enjoy having tactical advantage at all times,making incall always a bit safer, and less risky, along with being selective in whom you will see! Especially in an election year!! Q
