Demand for Attention
Medical services are not like business transactions where people can shoo you away if they are busy. Health is the main issue here and if you are feeling something abnormal, exercise your right for attention.
Most medical groups today know this and risking non-attention could lead to something serious if they do not address the situation immediately. Worst, if the illness becomes worst, they will become liable to the patient and of course this will spread as a bad image for them.
As you can see the medial service field is quite delicate. One false move and it could spell doom for you.
