I have always believed, absolutely, that any neurotic who finds herself in a position of power, however tiny, and abuses that power, should be forever banned from any future opportunity to throw her tiny tantrums.
Attorneys seem to have that universal affectation. "Please call me Bartholomew"
To which I immediately respond, "please call me MR. [my last name].
Works for me.
Incidentally, not to belittle the rule of etiquette, I never presume to call anyone I've just met by any nickname whatsoever; for the record.
