I am from the South, and it is true, that most people here do call each other "hun" or "sweetie," but my mother actually brought this up a couple of months ago. She is 48 yrs old and she despises when some 20-something or 30-something calls her "sweetie." She finds it extremely rude and disrespectful. She said she would tolerate it from someone in their 70's or older, but not someone younger than she. While I think that some patients may be ok with it, or even like being called those names, a lot of people find it unprofessional. The patient's name is acceptable all across the country.
