Yes, back in the seventies and eighties there were always two types of operators. The clean operator who ran legitimately and the other type for whom the pinball machine was just a front for major money making gambling machines.
We always new which locations to approach to try to place a pinball in and which ones you never approached if you wanted to stay healthy. It as very clear cut.
Happily those days are long gone, and we have all worked really hard to present pinball as a family freindly machine, so in a way it is a shame to have the stigma return in the series(although I did laugh when I saw the machines in Trimboles shed).
