That's exactly why I said "normally."
'Normally' shouldn't really have any place in this industry, when the consequences could be dire.
What's the longest journey it's possible to make with the airlines? 36 hours all in? Shouldn't it be possible to go without a drink for such a, relatively, short time? Don't get me wrong, I enjoy a glass of bubbly and a nice red with what passes for food on board, but it's a privilege which should merit serious consideration in this day and age.
