Years ago my optometrist referred me over to an ophthalmologist for some additional testing that he couldn't provide.  At my next eye appointment by optometrist asked what I thought of the ophthalmologist.  I said that I thought the guy knew what he was doing but there definitely was no asking how the weather was.  The optometrist paused for a second and then said he wondered about that when he saw the increments the guy was using for appointments.  My optometrist retired a few years ago and his replacement sent me to another ophthalmologist last year for my cataract surgery.  She didn't pause all of her work to chit chat with me all morning, but there was enough human interaction for me to feel that I was a patient rather than a dollar sign to her.  I like that feeling and I want my clients to have the same feeling.  But like I said before, we all have our own practices and our own way of doing things and we do what works best for us.
