Nobody likes going to visit the doctor. It usually means there is a problem. A problem for which you are looking for a solution. Here is an all too common conversation between patient and doctor:

Doctor: How can I help you today?

Patient: I have a terrible pain in my knee.

Doctor: What did you do?

Patient: I was tackled while playing soccer and fell awkwardly. How much will it cost to fix my knee do you think?

Doctor: We will need to run some tests.

Patient: Ok, the tests will be free I presume. I really just want to know approximately how much fixing my knee will cost.

Doctor: Tests take time, and give us an accurate picture of your problem so we can provide a solution. And no our time (and expertise) is not free.

Okay, that is not a real conversation. Nobody would ask a doctor such cost based questions. In fact as soon as we walk in the door of a doctors office the $ clock starts ticking.
