Age Twenty, Sarah Is Working as a Checkout Clerk in a Grocery

age twenty, Sarah 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. She doesn't have a steady boyfriend, but she dates quite a lot and is looking forward to getting married and settling down-although she guesses that she will probably have to work after she is married.
