It shits you doesn't it. I put $2 in a Scared Stiff at timezone the other week and could barly get the ball out of the shooter lane. The flippers were also rooted, basically no strength left in them and the rubbers had been rotated to within an inch of there life and barely hanging onto the flippers.
There was a heap of other issues as well but the worse thing is kids come along and get there money ripped of them and they walk away thinking jeez I'll stick to the other arcade machines, pinball is shit!
I told the staff (themselves just kids) about the problems with this particular machine and the response was that that's how this machine always is but they'll let someone know.
