Ms. Triptan: "Hi, I need to get in to see him tomorrow. My headaches have gotten worse."
Mary: "We're closed tomorrow. It's a holiday."
Ms. Triptan: "But this is important. I'm really miserable, and need something done! Couldn't he meet me there? Just for a short while?"
Mary: "No, but we had a cancellation for today, at 4:15. He can see you this afternoon."
Ms. Triptan: "I can't do that, I'm going to the casino. It's Bonus Slots Thursday."
