A very friendly seeming woman comes in with her husband. She stops at the customer recommendation shelf and says “Oh, honey, look a Feynman book!” Hands it to him, and then wanders over to the new comics wall.
The man flips through the book, makes approving noises and says “I’m going to buy this. Thanks, honey.”
She puts her books down on the counter and asks “What is it about?”
He says “It’s a graphic novel version of his autobiography.” Which is close to correct.
She scowls. ”Oh. It’s a picture book. That’s kind of childish.”
And I ask “Would you like a bag for your My Little Pony Friend Is Magic comics? Ma’am?”
