The sign is a GREAT idea! I think sometimes people just aren't thinking when they are putting food on their plates, and with all the choices and selections, it's a bit overwhelming and you can get caught up in the moment. A sign would serve as a reminder. Let's face it, food costs money, and quality food costs more money. Every piece of wasted food is being paid for by anyone who books a cruise, so it makes sense to only take what you will eat to help keep the cost of cruising affordable. The other scenario is even worse - instead of raising cruise fares to continue to deliver quality food, the fares stay the same and the food quality starts to suffer. It's a very good observation Phillip, you should suggest the sign idea to Carnival if you haven't already. Who knows, maybe they'll offer you a nice discount on your next cruise for your suggestion!
