This is the thread that just keeps going and going. On a recent, brief 6.5 hour, PHL-AMS flight I was seated in coach. When the meal service came around with drinks, I said to the F/A: "I'd like 6 Vodkas, 2 cups of ice, and a cup of lemons so I don't have bother you any more". He had no problem selling them to me. Maybe I was driving when I arrived, maybe I wasn't.
Nobody seemed to raise a fuss that I was consuming so much.
