Welcome to my world, Kate

So the other day my younger sister Kate was shopping at Food Lion. The young cashier was apparently new on the job. After he rang up her Mike's Hard Lemonades first, he realized he made some sort of mistake and called over his manager. She explained to him what he did. She further instructed him to "make sure you card anyone that looks under forty. Like right now, you don't need to card her."
Of course, if Kate looks over 40 (which she doesn't), I must appear......
