A: I need to request a wake-up call for tomorrow morning. B: What time do you want the call? A: I need two calls, one at 7 and another at 7:15. B: We can certainly do that. Expect a call from us at 7:00, and then again at 7:15. A: Actually, can I change the latter wake-up call to 7:30 am? B: I can certainly do that. Is there anything else? A: I can't think of anything. If I do think of something, I'll be sure to call again. B: Okay. Good night, sir.
