Would you like anything to drink?
Speak as Fred
Speak as Kathy
Kathy: Sure. Do you have any peppermint tea?
Fred: I don't have any peppermint tea, but I do have Earl Grey tea and chamomile tea.
Kathy: Do those have caffeine?
Fred: The Earl Grey has caffeine, but the chamomile is caffeine-free.
Kathy: In that case, I'll take the chamomile, please.
Fred: Do you not drink caffeinated beverages?
Kathy: I do but only in the morning. If I have caffeine now, I won't be able to sleep tonight.
Fred: I see. I'll make you some chamomile tea now.
