Workin' 10 to 4

A local yarn shop moved to a new location this week.  Their new shop is right between my office and my home, so I was pretty excited about the move.  Or at least I was until I checked their shop hours: Monday through Saturday 10 to 4, with extended hours on Wednesday.  Until 6:00.  6:00 is late? To whom, exactly, are they planning to sell their yarn?   

I think I want their work day, though.
