As Tim Ferris shows brilliantly in his famous book (four hour workweek) "Firing customers" can be greatly benefitial to all. Or, to stay in your analogy: striving to make a food that is 100% safe for 100% of the people will result in bland, poor food. It's fine to use gluten in your bread, or peanuts in your sause, even if x% of potential customers will get sick and can die, if they eat it. Fire those customers. Be clear: this is not for you. It makes the other customers happier. And consequently your stakeholders happier.
