You are in the kitchen cutting some lunch meat for a sandwich and you give yourself a serious cut on your thumb. You get blood on the cold cuts and on the bread, too. After cleaning and bandaging your injury, you return to the kitchen. There are blood spots on the meat and your bread is red and wet in one corner. Worse, you have no more fixings in the house to make another sandwich.
Do you throw it all out and make something else, or eat it anyway? Heck, you put your thumb into your mouth after you cut it just out of habit, but that bread looks like something from WARHOL’S DRACULA. Would you try to trim it somehow?
Eat the sandwich or not?
 If you don’t eat meat, pretend it’s some other ingredient. If you can’t eat gluten, pretend it’s GF bread. If you never eat sandwiches or cut your food or whatever, please don’t jump in to say why the hypothetical simply can’t apply to you, because that’s tedious.
