A long time ago on Qantas out of LHR i noticed one of the stewards was @issed out of his tree. I offered him my seat into which he promptly collapsed. I covered him with a blanket and made my way aft to the drinks trolley spending the rest of the flight to Bahrein watching the cabin "Manager" searching franticly for his lost crew, On approach I woke him and he made his way apparently sober to the service area
