I had a small run back in the day - I remember a SI table (black & white) that was sited at a gun club in Brisbane.
We used to do our collection run on a Friday.
Received a phone call Sat afternoon to say "the machine is full" - yeah, right - that was ALWAYS the call when a coin mechanism was jammed. Drove to the site to find a HUGE gun competition going on at the club and about 30 kids lined up at my second table (don't remember what it was).
Sure enough, the coin box was full - emptied it into a bag and went to the office to count it - $700 and that was in $0.20 cent pieces!!!!!
That was taken in one morning basically - they must have all been shit players to pump that many coins into the machine
