Do your clients leave angry? Pay attention to your patients' needs. They can leave the hospital if they wait for too long! However, this won't affect your progress. It is only an indicator that some improvements have to be done. You can minimize angry customers by improving each step of the business process. Upgrade your reception, rank up your consultations, hire the proper doctors, do related research, etc. Develop your own strategy! 

What are the symbols over their heads? Patients will arrive at the reception and will be addressed to the proper medical department. Those symbols represent the type of treatment, and clients will go to a specific waiting room accordingly.

Can't you see new clients coming to the surgery department? That's normal! Take in mind that all the departments should be at a high level to make it work. You can use the reputation points and the skills available to ease the pave! Don't worry! You're doing a great job, and patients will come shortly!
