Not Sunday, but: long ago when I lived in L.A., there was a tire retailer named '4 Day Tire Store' - their business was built around having their stores open ten hours on Thursday through Sunday, and not being open on Monday, Tuesday and Wednesday.

They claimed that these were the hours that most of their customers wanted to buy tires and have them installed - they also stated in their ads that this policy allowed them to operate the stores with a single work shift, reducing costs and allowing lower prices.
