When a patient goes to see a doctor, three things always happen in that consultation or treatment room as the case may be. The first thing is order. They keep asking questions until their patient has completely described the problems themselves. By the time they go on to say what the patients need, the patients are already in agreement that something is wrong. An average sales person doesn't know this they actually reverse the order, the speak and keep speaking first.
I understand the angle you are heading to, but there are many other strategies to use if you want to get more clients or customers for your business. In business, you don't just give a customer or a client something without them asking (unless they are curious); by doing so, it shows that you are desperate or probably don't know how to interact with clients. My whole point hee is that you need to understand what a client wants before you start giving anything (unless you are advertising your service).
Doctors allow their patients to do most of the talking first. First lesson; allow your clients always speak first.
How do you do it then?
Do you go straight to the hospital, and the doctor starts giving you drugs without knowing what the issue is?
The doctor needs to know what the problem is, and they cannot know unless you tell them. They also need to do some tests before treatment can continue.
The only time treatment will be given without you explaining the issue is during an emergency.
