Adorama and B&H, photography stores in NYC owned (IIRC) by Hasidic Jews, are closed on Saturdays. IIRC, they don't even take online orders.

imo this is fine, i mostly use them for business purchases, which i usually dont need over the weekend (its fun to go to their store on lazy sundays though...)
Perhaps. Hadn't check recently.
You also get signs like "Will be Closed for Yom Kippur" like you see signs for "Closed for Easter" etc.
