The family had finally gotten their first dishwasher.
The father liked to inspect every new thing that
came into the house, so he stayed in the kitchen
and watched the display count down all forty-four
minutes of the dish-washing cycle.

Suddenly he called out for his wife, shouting, "It's
useless, the dishwasher is useless!"

The wife was amazed that the newest appliance
could be broken after only one use, but he insisted
that because they had a water softener, the
dishwasher was useless.

She decided to look for herself, and there it was,
on the inside door, next to the detergent dispenser:

"USE LESS WITH SOFT WATER"
