1 - You are going to Dr. Johnson's office.Thank you.
I have two questions:
1- I'm asking because in my country, a doctor usually has their own private place(not shared with other doctors). So, in that case, should I say: I'm going to Dr.Johnson's (office or clinic) tomorrow?
2- There are also places where you can find a group of doctors. It's more like a small hospital but only for outpatients; patients cannot stay there. They only go to see doctors for consultation. Will that be called a "clinic"?
