Some of the New York camera stores are closed on Saturday (the Jewish Sabbath) to this day. I think there's even one or two that actually disable ordering from their web site on that day.

A state I lived in as a child allowed grocery stores, restaurants, and pharmacies to be open on Sunday, but not much else. Restaurants were also allowed to sell alcohol on Sunday, while liquor stores weren't. A local restaurant took advantage of this double loophole and put in a drive-through booze window that they only opened on Sunday.
