."We want 18 miniatures of Jack Daniels and 6 cans of Pepsi".
Now I may be in danger of revealing too much about my age, but wasn't there a time when a 2 drink-limit was imposed on some carriers? (... probably in the USA)
Now I know that this will certainly hit on-board revenue, and sadly cabin crew commission, but might it not be possible to reinstate this rule for certain destinations or certain times/days on carriers where 'sobriety' and 'decorum' have never reached the ears (never mind the brains) of certain passengers?
