As others have said upthread, by not reporting this it makes it acceptable. Now there's nothing to say that reporting it will change anything, but at least you did what you could and the ball is in AA's court at that point.
Unfortunately service like this is all too common now. It's really unacceptable when there isn't even a meal service to prep for (not that that really should change anything). When the only offering you're providing is a beverage and a bag of chips, you should really focus on being able to do those well, I mean, how much effort goes in to pouring a drink?
