That is exactly what most vegans do. No one is forcing restaurants to do anything. Most vegans are simply asking for more compassionate choices. A good restaurant serves more than just good food. For a lot of people, whether they return to a restaurant or not is not solely dependent upon the food they ate. Public establishments should have good customer service skills. They ought to be willing to listen and adjust to those that would walk through their doors. It is their business and livelihood and reputation at stake. Treat a customer like gold and they will never want for a customer again.If you don't like what they serve go somewhere else. No one should be forced to comply with whining vegans or anyone else. They can sell what they want and if it's good they will have plenty of customers.
