user: How are you? Can I get a Mocha?

assistant: I am sorry, we don't have Mocha on the menu. Do you mean a Macchiato?

user: No, I was wanting a Mocha. What kind of teas do you have? I guess I could get a tea.

assistant: We have all kinds of teas. We have black, herbal, and oolong teas. Would you like to take a moment to look at the menu?
