One thing i see alot of people doing when they play pinball (which is totally not required at all) is really bad slapping of the flipper buttons/or just hard slapping of the pinball.  After seeing this done by quite a few people when i visited Sydney last, it left me saying no wonder alot of sited machines have bad hand wear marks all around the flippers.  A good thing about having machines sitting closely and side by side, is that slappers cant get a big swing for a big slap, leaving them to play normally. 

Its also annoying because there is a constant amount of loud slapping which puts you off your game when playing nearby. The other annoying thing is people yelling loudly when playing a pinny, another pain. I like to hear the machines audio, not people yelling and slapping the shit out of your machine. I should put up a sign, "No slappers or yellers allowed".lol     There should be some sort of pinball finishing school for the masses.

Question -How do u nudge someone elses pinball machine, I say carefully and always ask first incase people dont like that etc. Respectful and gentle with someone elses machines. And u dont know what the tilt settings are like either, so best to always check first !

mate i agree. our shop pin is slap buy these yahhoo's who think they are pinball wizards lol. you see the wife having ago or the kid and the dad jumps in saying ill show you how its done and he starts slapping the buttons, lucky it not every one but its often enough you can almost predict a guy who is going to slap the buttons. as soon as he says he a is a pinball wizard from way back he will slap the buttons ahaha. its worst when they have a ring on. i dont nudge machine but people should always be respectfull to other people property
