I just heard in conversation:
César: Remettons nous au travail. Et plus vite que ça.
Another colleague: Bien sûr, César ! Tout ce qu'elle voudra !
I assume this expression is similar to "à vos ordres". The thing is that one of my colleagues, César, is male through and through, so I wonder why the pronoun "elle" was directed at him, instead of "il"?
