When I worked at BWI cateromg a few years back, those flight crews were always calling us back. " Not enough bottled water, " " Short on coach meals," " We need extra wine in first class," etc. My point being that back then it was rare that the flight crews missed anything. It's too bad times have changed and even though I don't know the extent of what happened...( like possibility of turbulence)....you at least deserved an announcement that there wouldn't be a beverage service.
