I'm sorry to have to do this, but the owner of this place is a jerk.  I got yelled at, for playing pinball in a way that has helped me play very well in pinball tournaments and leagues over the years, and not one time has anyone, including the owners of some very rare and valuable games, mentioned anything to me about abusing a machine.  But that wasn't the case here at the Pinball Hall of Fame.  Instead, I was told (in a very confrontational way) that new Stern machines were all made of plastic, the flipper buttons (of course), the sides (huh?) and the legs (did he really just say that?!?) and that I better calm down or I would be asked to leave.  BULL$HIT.  He treated me like a moron--flat out lied to me thinking I must not know any better.  This was after he stood about 5 feet away from me with his arms crossed watching very disapprovingly as I would hit the side of an Avatar machine to keep the ball from exiting the right orbit and dropping into the right sling.  Watch just about any pinball video or tutorial and it's pretty clear this is the sorta thing you have to do to control the ball and continue playing.  It also does absolutely nothing to harm the game, and hitting the side with a sledgehammer certainly wouldn't have caused a pop bumper to be non-functional, or the one-way gate at the top of the left orbit to be jammed up, as they were on this particular machine.  It also wouldn't have caused AC/DC to be about 5 degrees off level.  And to make matters worse, I never encountered a tilt warning on AC/DC, Avatar, or the one EM I played before I was warned for a second time for making a very light slap save.\n\nI would think that Mr. Tim Arnold, of such long standing participation in the world of pinball operation, maintenance and collecting would know how to set a tilt bob to prevent players from being able to move the game in the slightest, since that's apparently what he wants. I can now only assume that's much too difficult a task, and it doesn't give him an opportunity to eject people that obviously know what the hell they're doing on a pinball machine, and that might otherwise complain about the poor operational condition of most of the games in his establishment.  I chose to leave on my own after the second warning during which time I was followed out the door while continuing to be berated.  I have no desire to ever go back and give this guy another quarter, so he can flip it all to the Salvation Army (400k last year) while continuing to let his games sit broken and refusing help from volunteers to get them repaired in a reasonable time frame.  You'd think he could take some of that money and invest it back into the place but I guess that's now how he wants to do business.  It keeps the \""complainers\"" away.
