Bagger (Male): "So, I'm thinking that when we're ready to engage, I get her a ring, right?"
Cashier (female): "Yeah - that's usually how it works"
Bagger: "So then I'm thinking, when we get married, we can sell the engagement ring since she's going to be getting a wedding ring to replace it."
Bagger: "Cause you don't need more than one ring, right?"
Cashier: "Have you discussed this with your girlfriend?"
Bagger: "No - I figure we'll talk about that when I make the proposal."
Cashier: "Yeah - good luck with that."
