Tedious myth

I don’t go to the doctor very often. Which is a good thing. But on the rare occasions when I need to make an appointment, I have never met a “dragon” at the reception desk. Nor has anyone else, who has had my newspaper brandished at them after I’ve encountered this tedious cliché in some columnist’s efforts. Could we kindly bin this expression; except when the columnist is prepared to name names and publish a photograph to make his/her case?
