It is certainly not unique to the medical profession.
But few
non-military fields are as vicious. In auto repair, the newbie would be
sent to get spotted paint, rubber nails, and a metric Crescent wrench (all
of which actually exist).
When I stareted (physics) research, they sent me to get a 'bucket of
steam'. Of coruse I realised it was a hoax, but decided to play along. I
got a bucket and filled it to adepth of about 2cm with water. Carried it
up to the hoaxer and poured it over him with the comment 'sorry, it
condensed on the way up here'.
My favourite thing to send people to stores for was a 'monochromatic
white light source' :-)
