Restaurant business. The customer isn’t always right. In fact you aren’t a customer you are a patient and too often with patients the dunning Kruger effect is fully apparent. As a physician I try to make decisions that are cost conscious but sometimes the right decision costs more because not doing it right leads to higher morbidity and mortality. And lawsuits. I’m sorry you had to pay more, but in medicine we aren’t dealing in $20 meals we are dealing with lives. 99.9% of the time it looks like eczema, 0.1% of the time it’s cutaneous T cell lymphoma. It can look exactly alike. Makes a big difference though. Same with moles and melanoma. Every dermatologist has had their fair share of benign appearing moles that turn out to be something not so benign. We share the pictures with each other and freak out about them all the time. They keep us up at night. So we test a lot of things but we don’t have a good way to know when it is 100% safe to just throw things away.
