Restaurants should not waste food, manage their resources effectively, and distribute the foods to the customers efficiently, why? It's because food resources are scarce, therefore, make use of them to it's fullest extent, there are people out there who doesn't even have foods to consume. Restaurants should imply this ideology, because most of them don't, even the most successful restaurants tend to waste their food resources, be noticed that by managing the food resources effectively and distributing the foods to the customers efficiently in a frugal way is a double merit to the restaurants themselves; one, lower expenses, since less food resources are being used, and two, indirectly helping the Mother Earth and those people who're experiencing famine. Even little things like pepper, chili, salt, etc are also important, don't waste them and take it for granted, because it accumulates and will have a great impact on poverty later on.
