you're at the deli counter and request a half pound (or so) of your favorite deli meat/cheese. the deli clerk looks around and doesn't find an open package that he can slice so he takes a sealed package and breaks it open. super-fresh deli! ok... do you stick to your original request or do you increase the quantity? me, i always increase. i figure that with a fresh pack just opened, the meat/cheese will be tastier than one that has been sitting opened in the deli case for an unknown time and that i'll be inclined to eat more and forego eating something else.
