I have never cancelled due to illness as I am not usually sick. T tells her clients if they are sick she would rather have them cancel than come in and make her and possibly her other clients sick. She doesn't charge for missed appointments either regardless of the reason. I did once call her as I had been sick and still had some residual symptoms of a cold this winter. I told her what was going on and asked what she would prefer as I felt fine but wanted her to decide. She told me to come in.
