My mother always had us set the table - knife, fork, spoon. When I married and realized MIL only put on the table the flatware she expected diners to use, I was a bit discombobulated. It certainly wasn't wrong, but it wasn't the way I'd been taught. I still set the table with knife/fork/spoon, even if the spoon or knife won't be used.
(and anything put on the table gets washed before being returned to the cabinet/drawer - it was handled, so it must be washed!)
