What about if she had no money on her person at the time of landing there and had to wait for relatives in France to wire her some money? Would it have been possible for someone to take her in for the time being or would she have settled for a cheap hotel?
It seems improbable. 1st class passengers, even if they lost their immediate cash, had connections that could be tapped readily. A letter of credit or a wire transfer would have taken care of the immediate financial problem.
