I have an honest question: why does it matter to whether one gets Champagne 15-20 minutes earlier or later? It’s not that passengers spend hours on board without liquids. Typically they have spent time in a lounge before (where certainly there is some Champagne), and as soon as doors are closed the corks are popped as well. We are really talking about that small window between leaving the lounge and the aircraft doors closing. Does that really matter?
