i understand the dilemma ... i often wonder whether to ask for two bottles to save the CC extra leg-work getting me a refill, and whether that then makes me look like a drunkard. The
pre-dinner glass of wine often means that there's none left when the meal arrives, and the last thing I want to do i ask for another bottle in the middle of meal service.
As Avman noted, sometimes they can't stop offering refills on some carriers. I used to have to stop MaxJet trying to get me unfit to drive on arrival!!
