I've been fortunate to have really good doctors who honor their appointments and seem to be very caring.
A few years ago, I dropped a skin specialist who always kept me, and everyone else, waiting from one to two hours. She wanted to know why I wasn't making another appointment and I told her. Didn't bother her a bit.
Now I can count on my skin guy seeing me within minutes of my appointment. Once he was about five minutes late and he apologized profusely.
