Not The For Richer Or Poorer Type

(I’m seated next to a couple who seem to be on their first date at a popular South American themed restaurant. The guy is talking rather loudly about some time he spent in Argentina.)

Guy: “…and Argentina is so cheap because they have exchange rates down there. Do you know what an exchange rate is?”

Girl: “Um… no…”

Guy: “It’s like this. The exchange rate is seven pesos to one dollar! If you bring $10 you now have $70! You’re seven times richer!”
