You cannot cry out-loud that you do not have privacy when you do private stuff in a public place.

Is like walking naked on a beach and you start yelling at people watching you, to give you more privacy.

If you really have to do stuff in a public place like internet, then use virtual nyms that are not related at all with your real you (the living man).
