Seems I need to clarify things a bit.
I was at an arcade where all the machines throughout the place run off of cards. This particular arcade has a "time play" option where you pay one flat fee for all the games you can play in a certain amount of time. Redemption and the newest games don't work with time play, but the pinball machines do. These pinball machines (Kiss, TWD, ST and MET) are located away from the main arcade floor, in the bar area.
I was in the arcade at around 11AM, having just completed a job interview. There was absolutely nobody else in this section of the arcade for HOURS.
You have to wait 90 seconds before you can use your card again when you have free play enabled. And these pins had the "3 games for 2 credits" price in effect. So I would scan my card, wait 90 seconds, scan it again, start playing the credits. I was moving from machine to machine, stacking up the credits. Like I said, this went on for at least a good two hours, with no one at all coming into the pinball area.
Please keep in mind that if the pinball section was crowded, I wouldn't be doing what I was doing. I'm going to mention again so it's perfectly clear: THERE WAS NO ONE ELSE AROUND.
So I'm playing Kiss, trying my damnedest to get on the leaderboard, when the family in question walks up to the other machines and just starts going for it. They went through ALL the credits, even starting a 4P game and walking away. Is that awesome? Is that the kind of thing you do, pinplayer1967? 'Cause I think that kind of behavior is deplorable. It's rude and it's inconsiderate. These weren't little 10 or 11 year olds, this was a GROWN FAMILY who knew credits don't magically appear on gaming devices.
I'd also like to add that it's really rude and inconsiderate to pull the "I can't believe adults have to explain this to you" card on me. I take it you were born in 67, according to your username. I was born in 73. Yes, when I was 10 or 11 I would play anything left open. I'm Forty Effing Four now and I would feel ridiculous doing that.
