Refrigerator magnets

Lois looked at all of the refrigerators and compared their features, but she couldn’t make up her mind which one of them to buy.
The salesclerk said, “I think I can help you.” He led her to a circular room with refrigerators of every brand and model along the perimeter.
Then, he handed her a refrigerator magnet.
“Close your eyes and spin!” he commanded.
She did so.
“Now… throw!” he shouted.
She threw the magnet.
“Stop and open your eyes,” he said.
She’d thrown the magnet at the door they came in through.
“Just buy the damn Whirlpool,” he sighed.
