Perhaps yes; perhaps no. Specifically, everyone being able to get what they want invariably raises costs. Should the 90% of patrons order the same 15% of menu items pay so much more because the costs of the eatery are substantially driven-up by the fact that it carries the other 85% of the choices to serve just 10% of the patrons? Clearly, that would be unfair. By the same token, charging $5 for a hot dog and $9 for a soy dog would make Disney look bad for so grossly "punishing" vegetarians. These kinds of considerations reasonably drive decisions to limit what any one eatery offers.
