In this clip, the doctor gives direct instructions to the surgery receptionist to get an ambulance as quickly as possible to a patient (Mr Lindley).
The receptionist is concerned with the fact that the doctor wants to see Mr Lindley, as there are patients waiting for the doctor at the hospital. The doctor replies by saying: "They'll understand. I shan't be long."
The receptionist follows the doctor's instructions by saying: "All right, doctor. I'll phone for the ambulance now and I'll talk to the patients still waiting." The doctor is clearly pleased at the receptionist's response and understanding.
