In France, it seems shaking hands and "ritual" kissing is the norm--even between men.
In another post in this thread, Geneva (in the French area of Switz.), kissing is mentioned; in the German and Italian areas (of Switz.), I've rarely noticed lots of handshaking.]
That is not the norm for my initial business meetings in France or Francophone parts of Switzerland.
The woman mentioned in the OP seems to have gone way overboard in the response either way.
