So after buying a cup the other day, winning, tearing off the lip and redeeming, I had an immediately obvious idea on exploiting a glaring flaw of this system and I am absolutely dumbfounded no one has thought of/tried it yet.
I'm led either to believe everyone is clueless or there is some advanced security system that I am not aware of...
So I ask you intelligent people to posit what it may be, and what, if any, are the preventative measures?
