I think myself a sommelier of medicine. Not only selling drugs but also communicating with customers is my mission. It is important for customers to know the most effective usage and compatibility of drugs. If I find the customer the importance of visiting a hospital, I advise him to take medical check up first. Recently many customers from overseas to come and visit our shop to buy many over-the-counter drugs as souvenirs. Before we sell, we want to talk with them first and know the health conditions and then advise them which the most suitable drug is.
