Worked in retail awhile back. Kept having glass shit fall off displays and ends. It wasn't TOO often, just enough to be an annoyance. They were stacking glass product on top of one another. I explained why this was a problem; they didn't care. Some time later I came back to the bosses with an argument:

This is how much we're charging for the product.

This is how much I make per hour.

Cleanup of said broken product takes X time.

This is how much I make in that time, or Y.

Which means a single broken product that breaks costs you Z, multiplied by the number of times it happens, plus the cost of the product itself.

This was what got their attention. These people usually aren't human, they're sociopaths. Remember that.
