What is the man’s occupation?

W: Mr. Shaw is here for his 10 o’clock appointment, Dr. Lee. Do you want me to send him in now?
M: Could you give me five minutes, Sarah? I need to make a call to my accountant first. Also, did my wife call by any chance?
W: No, I don’t think she did, but I am not sure. I had to step out for a few minutes earlier to pick up something from the X-ray Department on the second floor. Do you want me to call her and see if she did? M: No, that’s fine. I’m sure she would have left a message on my pager if she did. Anyway, please give me five minutes before sending in the next patient.
