Nothing fancy, but this stunt could cause the demise of one of these machines, plus the spillover ill will of ear-mushed customers toward the restaurant or bar.
Out a bunch of your abandoned change, two or three dollars’ worth, into the target box and select the worst song on the play list. Researching the establishment, its patrons and the play list for maximum effect is vital before you attempt this stunt.
A bit of test marketing could also help you. Select the absolute worst song, the really aural dog on the list, and pump it all your change. Hit the buttons and leave or stay; either way, enjoy.
