At Age Twenty, Sarah Matuzek Is Working as a Checkout

At age twenty, Sarah Matuzek is working as a checkout clerk in a grocery store, having left school after high school. She didn't do particularly well in school and had a hard time learning how to run the cash register, but she is a cheerful person, outgoing and friendly, and a reliable worker.
