Where are the woman and boy going?

F: Wait. I almost forgot one thing. Our refrigerator is empty. We must go to the supermarket.
M: Must "we"? I mean, why not go there yourself?
F: Come on, boy. You’ve got nothing better to do.
M: Okay, then.
F: Let’s get a shopping cart. First, we should get our vegetables. Potatoes, tomatoes, onions... what else do we need?
M: Don’t ask me. You are the one who decides.
F: Ah, yes. We need some bananas. Let’s check out the fruit section.
F: Look at the fresh strawberries. Must be delicious. And, here are grapes. I’m always crazy about grapes. Next is the meat section. Want some beef?.
M: Mom, I think we’ve got more than enough. And if we don’t hurry up, we’ll miss the dinner time.
F: My! It’s already 6 o’clock!
