Etiquette Question/Deep Thought or Whatever

Is it rude to politely decline a consumable such as tea, cookies, etc from someone if you know you won't consume it and will just throw it away once they are gone? This way it is not wasted.

Or is it better to politely accept it and then throw it away once they leave. What if they search your trashcan when you are away?
