Just as Vomiting Cop can demonstrate that someone in law enforcement isn't (yet) jaded about gory death, this trope shows just how jaded someone who works with dead bodies can get. Whether they're a Creepy Mortician showing an abnormal indifference to morbidity, or The Coroner whose mid-autopsy noshing is being Played for Laughs, expect all but the most sober of works to show people in the funerary trades munching sandwiches or french fries, or at least sipping coffee, while they've got a body on the slab.
