It’s only fair to “demand action from others” if such “action” is something that the provider provides for their other clients.
The argument of “I should be able to order a ham sandwich from a kosher deli” (or similar product-related arguments) doesn’t work here, because if the kosher deli doesn’t provide ham sandwiches for anyone, they don’t have to provide one for you.
Likewise, if a bakery doesn’t provide wedding cakes as one of their services for anyone, they aren’t required to provide a wedding cake for your wedding. However, if they provide wedding cakes at all, and if you have the money to pay for one, they must provide you with a wedding cake.
See how that works?
