Sin Eater Eate of the Victorian era

In the Victorian era there was a position one step further down the social ladder than the infamous chimney sweeper.
This position belonged to the awful figure of the professional Sin Eater.
Below is a Sin Eater Guide:
Step one a person dies
Step two the family of the dead arrange a  funeral and  hires a Sin Eater
Step three said Sin Eater attends the wake and consumes bread and salt from a plate on the body of the actual corpse
Step four the other people who attend the funeral abuse and beat the Sin Eater as they leave.
He or she is kicked up the arse by a dozen boots which  must have left a mark
Now you are ready to start!
It is really dark the  Sin Eater literally consumed the sins of a fellow human and was paid a pittance for offering the deceased the priceless chance of redemption leading to salvation.
What an awful occupation risking eternal damnation for a few coins and a light lunch.
Even worse in that time there was no milk and magnesium, renees or even Gaviscon.
  Can you imagine the poor sods indigestion?  
Do you think Sin tastes like chicken?  
I  suppose it could have been worse  If they were allergic to gluten.
 The truth of it is you should always look on the bright side of your job even if your eating bread off a dead guy...
