Right to refuse service to people is part of the First Amendment as well.  Can you see our local luau businesses affected if they are required to accommodate those who do not eat pork?  Would the luau have to serve a beef or fish alternative to accommodate those with religious  objections to pork?  Even worse, would the luau be forced to take kalua pig off their menu?  Can you see how ridiculous these cases are becoming?  Common sense dictates, if someone doesn't want to work for you, you just find someone else who will!  Forcing this bakery's owner to violate their religious beliefs is just about as bad as asking a synagogue or mosque to serve kalua pig at their dinners or functions.
