It was my fault for forgetting about my appointment but isn't a $75 no-show fee kind of high? It was only supposed to be a 10min appointment to go over blood test results. I don't know what other clinics usually charge but according to this article:
"The fee should reasonably reflect the cost of the missed appointment, which would in general be about $30 for a regular appointment and $60 for a full physical."
