Mimi Pond is a treasure, one we ignore at our own risk. Decades ago, she left her mark on television by penning the first episode of The Simpsons and writing for beloved institutions such as Pee-wee’s Playhouse and Designing Women, but her greatest contributions to popular culture have been her cartoons and illustrations. She’s created pieces for an array of publications and periodicals, but her latest book — a thick, semi-autobiographical bildungsroman called The Customer Is Always Wrong — might be her greatest work to date. It’s a lengthy and detailed portrait of a young woman working at a restaurant in late-’70s Oakland and the cast of characters around her — some of them shady, some of them lovable, and all of them compelling. Pond’s hand is confident and her figure work hops balletically across the page; her facial acting is simple, but searing. It’s a long journey from page one to the end, but you’ll be glad you stopped by for a cup of coffee or two with the folks Pond conjured up.
