Dear dermatologist's office,

You put me in the exam room farthest away from the front desk, and then you forgot I was back there. I waited almost an hour before I decided to see what was going on. Even though you denied it, it was pretty clear from the looks on the staff's faces that I had been forgotten about. You should have seen me at no charge that day. I'm pretty steaming mad that you billed my insurance after you made me wait that long. Don't let this happen again.
