I would say : "are you out of your mind? " ok, that's a lie...I wouldn't say that... but I would be staring at the window hoping that some super heroe comes flying suddenly to take me out of there in that very moment ! ... because if you really need the job, the best I can suggest you is to say that you are opened to the possibility if the case worth it... and when the time comes you will have to stick with what you said; but remember ... once you are already hired , depending on the situation, you could always negotiate . =)
