A tough customer that I've had, that I won over, I guess one of my most toughest customers was a lady that I was taking care of, and I guess I can talk about her now because she is deceased, but she wanted her pain medication and she was a real beast, and oh boy. So I was very calm, and I helped her understand the system because we couldn't give her extra, and I explained the laws to her, and so when she had knowledge, she had power, and then she treated us better.
