It's no surprise that many professions cut corners and do some sketchy shit to make an extra buck or save themselves a hassle.

These are some pretty widely accepted (albeit unfortunate) truths. But u/CircleBox2, in the name of demystification, asked redditors to share the darkest secrets from their industries. And some of them are shadier than we expected.
