Luxury bones for smiling only.

Imagine if you cut off your middle finger in a factory accident, and the doctor would refuse to sew it back unless you pay large amount of money for it. When refusing to pay they'd say your middle finger is only for flipping of other people, and maybe you just flipped off someone already having a bad day, so you pretty much deserved it, and otherwise if it was done for cheap you wouldn't follow standard workplace safety measures. And finally, you'll get a cheaper "alternative" in the form of a non-functioning fake finger.
