Wasted food

Thanks to Maris Piper for this food for thought!!
We have a lot of 'all you can eat' restaurants here and it always make me crazy to see all the wasted food that people leave. Why pile your plate higher and higher if you are not going to eat it all. Is it the thought that you are getting a lot for your money? I don't know!! I've noticed recently that Souplantation now gives you a bowl to 'toss' your salad in, the idea that you put the tossed salad on your plate does not occur to some people and they eat from the bowl!!
