I own a vacation home in Lake Tahoe, CA. I have many arcade games for my guests to play and enjoy (Ms. PacMan ~ Galaga ~ air hockey ~ pair Rush the Rock drivers ~ Crazy Taxi ~ Mega Touch ~ Bumper Pool ~ 2 pinballs). One pinball was a White Water.
My clean crew didn't notice that one of my guests removed the dome and the waterfalls inside, on top the game. I've had a dozens guests in and out and wouldn't know which one who did. It's definitely a pinhead, which really sucks too.
