person A: Do you know anyone who spends a ton on eating out every week? It's crazy to me how much they spend.
person B: I know that when just the 4 people in my family do go out_comma_ it runs us about $65.  So we do it very rarely_comma_ it wastes a lot of money.
person A: Yes_comma_ exactly. A friend was telling me they spent almost $300 a week on eating out. I don't even spend that much on groceries. 
person B: A week!?  That is just crazy_comma_ and pretty irresponsible unless you are a millionaire.
