Just off the Koningsdam after an Alaskan cruise. Every menu in every bar lists the beer options as being 16 oz. Near as I can tell after trying to order several, none of the beers on board are actually 16 oz servings. It would seem the easiest thing would be to put a sticker over the 16 oz note on the menu, second easiest would be to actually stock 16 oz product.
If the food menu says an 8 oz steak, I don't expect to get a 4 oz version.
