Good operators leave contact info on the games, and are responsive to issues.
Good customers use that contact info to report issues.
If the game has no contact info, and the games are unattended, yes, I'll turn off a game that's flat out robbing people of their money. Especially if there's a bank of machines that are little more than honey traps. If it's something trivial, I'll leave it alone. Future gamers should not have their first impression of pinball simply be "that ___ box that took my money and did nothing".
