Not possible for a girl living here on long term basis or permanently, because she'll go insane.
Possible for a very popular escort that only tours here a week or two the most, as obviously she wants to get the whole benefits of her long trip and many expanses.
What I don't understand ... no girl is telling the first stranger coming into her bedroom that she makes so much money, at least the common sense would indicate so. In my opinion, this could be a lie or exagerated estimation of the newspaper.
