You don't fill a form, you set your table. You pick what you want from what she actually cooks, and you can open any dish and take out what you don't want. No scotch bonnet in your suya? Tap it off, and she won't buy it. Then you seat your guests and see them sitting around your table in 3D, with your food on it. The price breaks down as you go, so the "how much?" conversation just doesn't happen.
