"Unprofessional behaviour"

I came for an outpatient dermatology appointment in November last year. The doctor was an hour late but understandable seeing how London traffic is unpredictable. Here's the worse bit. I was made to feel incredibly stupid for not knowing my diagnosis since I was a doctor myself. The doctor I saw even questioned what medical school I went to. I would never speak to a patient like this and expect to be treated as a patient, Not a doctor. Horrendous behaviour. I hope their juniors do not learn from them.
