Rick, there is an important distinction between your example and the actual case. Any business can set its hours of operation, and there is no authority that can force them to change those hours. B&H could choose to open on the third Thursday of every month only and we would all have to suffer through that.
The tricky question, however, is who a business can be forced to serve. B&H, as a camera store, couldn't choose to serve just Jewish people, for example. So in this case, the question is what distinguishes a photography business from a company like B&H. That's what lawyers get paid to debate.
