You are welcome. As I am based in Tunis now, I don't think that you will be getting your boarding pass at the gate. TUN airport is not meant to be a transit area from my own experience. If traveling with Tunis air, then its a different story then. When is your flight? Can you kindly report back with some photos from your flight? I would to confirm if QR's new C menu and tableware setup is already rolled out on flights to TUN or not.
