I heard somewhat of a disturbing story today from one of the staff at my local arcade.
Basically it involved a electrocoin Diamond 7 that had recently been converted form £35 to £100 jp. Some woman had ploughed £800 into to get one set of 7's to roll in which didn't even hold (which to add insult to injury the hopper emptied as a result).
I can't even contemplate the thought of even taking such a high risk, i'd be utterly sick if that had been me. I could understand perhaps had it been £500 jp as you may have an outside chance of recuping something back, but for just £100 is it really worth it
