"Could I please have another drink?" is indeed a question.
BTW, those who suggest that the OP should have walked to the galley to get a drink should note that most airlines (including DL and KLM) have a rule (IIRC it's a FAA directive) that (alcoholic, but it also makes sense for hot beverages) can only be served to passengers sitting in their assigned seats.
