I hate it when I see a nail polish or fabric paint display that is completely encrusted with wasted product.
If I catch someone doing that I tell them they have to pay for it or I'll call the police for destroying private property (the display).
Whats worse is some places have little test papers for colored markers/pens and people STILL write all over the freaking display.
They should just make the displays pre-spattered with the product... OR even better, attach a 20 volt shock sensor to every cap that's only removed after purchase.
