    My personal career path lets me to speak on the issue professionally - any "intruders" constitute serious challenge for the business (Pc. [001]), and the level of clients shall correspond to the level of their privacy covering.

    The issue of the clients protection is wide-ranging, should hence be talked in person, but some its facets can be briefly placed here. Let's turn to real examples. First, the simple, physical security. Although it's from "those times" (Pc. [003], [004]), nothing is changed to our days - such pictures are being recorded by police agents all over the World. Without the consent of, let's say so - victims. And not a single case is known - on all the Planet, for all times, since, say, the 1930s, when on their's own initiative the police authorities handed over the photos to the victims; or at least inform, that such a surveillance took place.

    The issue becomes even more sensitive, when the surveillance is being done in private rooms. Indeed, needless to say, it brings little joy to have someone at the same time (Pc. [006]). It's on the privacy in the brothel. Yes, a client can say, he would like to invite a girl to an external hotel. But there also it can be the hidden video surveillance - from my personal experience I can cite at least one hotel, in Sofia, Bulgaria, where there were a hidden camera in the restroom - and the hotel managers knew it.
    It's mere an illustration (Pc. [005]), professional equipment shall be being used, to scan the rooms for any malicious recording devices.

    But, the more challenging is a behavioural dimension (Pc. [002]). Once again, this should be talked in person, but short - social values of the girls, human psychology, as well as one of those "intruders", are more or less palpable, and some measures here yet can be arranged.
    Some words can be said here on simple options, for instance, on identity concealing. No doubt, you know that story on 19 year old Princess Elizabeth, as on 8 May 1945 she blended into the London crowds anonymously, without being revealed - with her military uniform she looked like other servicewomen. But the following, unknown for the Western audience, ventures, without doubt, are of more significance. Saparmurat Niyazov, the President of Turkmenistan (Pc. [008]), was in the habit of going along streets - alone, casually. To stay in tune with rumors, moods among his countrymen, he listened talks of the people. To be concealed he used make-up (Pc. [007]).
    To hide a client, if he wishes, the same can be being practiced here - a girl cannot get to know, whom she had a sexual intercourse with. No, it's not an excessive "joke". And it's not about how to commit unpunished violence against the women - it's how to avoid to be identified.

    You should agree, indeed, it's a necessary measure for politicians, businessmen, who are in the focus of public attention.
    Their wives also shall not know, where they spend time.
