Bill, you are right on the button. One think that I have found that helps it either go with the intention of splitting with someone or when you order your food ask them to either put 1/2 in a box before you even get the plate or ask for a box with the meal and box it before you even start eating. It sound weird and I have gotten some strange looks but it really helps with the out of sight, out of mind mentality and I feel stupid if I asked for a box and don't have anything to put in it. If you don't want to ask before they even bring your food then take a few bites and casually say "wow this is a lot more than I expected, can I get a box." Hope it helps.
