Above and beyond it being caused by cancer, it could happen to a person burned in a fire (maybe while trying to rescue somebody), or born with birth defects.
The idea that looking odd due to damage from any of those things and probably a lot of other things, and people then refusing service to people like that, is really quite disturbing and wrong. People should know that the only real monsters out there are the ones who are twisted inside, not people fighting an illness or with a deformity.
