We as consumers choose with our spending power who we choose and do not choose to patronize with out business for many reason and yes those reasons can include the religious convictions of that business or for that matter even if you don't like the color of the pain on the walls. Where it tends to run afoul of the constitution in my humble opinion is when a local, state, and federal Govt. makes laws that deny a business a means to surivive if they comply with existing laws, simply because they have an issue with their religious beliefs. Chic-Fil-A no matter what anyone may think, is a private company and is entitled to it's owners opinions which has been very public for a long time, and as mentioned above if their business is in compliance with locals codes and state laws, then the only thing that remains is the consumer who is and should be the ultimate decision maker in their success or failure.
