I have upmost respect for other peoples property and would never eat or drink over their machines. I am careful not to damage anything in any way. I will always wash my hands after eating before I play and I am not a slapper etc...that said, I will nudge a pin as much as I need to make a save. If I am too agresive then I will tilt and learn the limits of the particular game. Thats what Tilts are for and if someone doesn't like their pins nudged they can make it more sensitive. Easy
