Cultural subtext: she did just give him an erotic foot massage.

Again. Availing yourself of a prostitute’s services does not make you a friend of the prostitute. It makes you their john.

The way I read that, is that a) Jesus stiffed her on payment (he did forgive her, after all! How nice.) and b) got irritated when the Pharisee called him out for… you know… getting an erotic foot massage.
