that's my point, if the machine played & looked as it should I'm sure the kids would give it a go and put in a few bucks. If it were me, I wouldn't even consider putting in a dollar, but then consider playing a game where the flipper chatters, sling is dead, missing rubbers. The game plays crap and you'd have to then form an opinion that pinabll is crap as you don't know any better.
I played a CV at a cinema complex and the flippers had no rubbers, there was playfield scrapnel all over the place. I played it purely to see if it was playable. It wasn't!!
