Shop assistant: Good afternoon. Can I help you?
Mary: Yes, please. I want to buy something for tea.
Shop assistant: We have got very tasty cookies. Would you like some banana cookies?
Mary: No, thank you. I’d like to buy a cake or a box of chocolates, please.
Shop assistant: Sorry, we haven’t got any cakes now.
Mary: OK, I’ll buy a box of chocolates then.
