I once had a train where somebody was collapsed at the buffet, and the customer host put out an "Is there any doctors on board?" announcement. He didn't know that there had been a dermatology conference in Cardiff, and a few dozen Dermatologist's turned up!
Given that dermatologist is the Greek for "Not a real Doctor", they all stand around wondering if the casualty had a rash while an anaesthestist who also turned up sorted the patient out. I handed the phone over to the most senior dermatologist to answer the questions from the 999 operator about the patients inside leg measurements after I had arranged for the ambulance at the next station.
The experience has made me wary of the "Is there a faith-healer on board?" type announcements!
Love the story!
Could have been worse - imagine if it had been a Pathologists' Conference.
"Sorry, can't help until he's dead ..."
Yes, I know pathologists don't only deal with the deceased ...
