I have a "rule" , if I see an unfinished game, I will play it through. example it's usually the 3'rd ball in the shooter lane. I'll look around to see if the player just hadn't stepped away for a moment. and ask if anyone is close by if it was their game. then play it out if none to be found.

Or if I see a ball search & the flippers are functioning I will try and un-loosen a trapped ball to finish the game.

I always wait to see if I match for a whole new game and celebrate (even if on freeplay)

Yeah sometimes I will get burned out on a game I had won a lot of credits on and will leave them for others.

If a major malfunction I will let someone know to hopefully fix the situation. if it's just a kid giving me quarters back for an obvious unplayable game I will turn it off.

So Thanks to everybody who leave a ball in a shooter lane for me
