What's Up...doc!

What is the Doctor doing after the nurse takes all of the vitals and asks all of the standards? When the nurse leaves and says, "The doctor will be right in to see you", you better be ready to sit in silence for 20-25 minutes. It feels like the DMV. Why are doctor offices so inefficient? You need to set aside at least two hours for any type of visit, regardless of the severity.

I think they should work on tips?
