This kid has to learn the art of NOT typing.
The word salads he keeps unleashing on his customers and potential customers say nothing with an incredibly large volume of words. This is NOT what people need to be reading, it comes off as a confused mosaic of excuses and non-sequiturs that will only serve to lose him business. The entire hodgepodge he crapped out could have simply been boiled down to "Our team is working to ensure our pinball machines are in top condition. Please bear with us as we make this a reality!" or something.
You are never going to convince people who are annoyed that your shitty collection of bargain basement, free, and dumpster find pinball machines are not working that they are not annoyed. It doesn't work that way. Tell them what you are doing about the problem and when they can expect it to be fixed. Don't talk down to your customers and tell them they are idiots for thinking a bunch of machines you promised they could play should be working, and that hey, we have a Galaga you can play instead.
The proprietor acted like a dipshit in various online arcade forums from Day 1, and that's great, he's entitled to do that and has taken advantage of that right just like many before him. But he's in customer service now, and simply can't behave the same way. Customers and potential customers are less likely than ever to respond well to that treatment, and since the only way most humans interact these days is through customer reviews, that's incredibly bad news for his new business venture.
Stop treating your customers like they are idiots.
Q: "Why don't you have the full size blue and pink Ms. Pac Man I remember?"
A: "You are a moron, the ugly, smaller cabaret version is way more awesome!"
Q: "Why are half of your pinball machines broken?"
A: "You are in idiot. It's more like 46 percent are broken, and also you moron don't you know that pinball machines are always broken that's just how it is, despite the fact that I told everybody I'm a pinball machine repair pro when I was begging for their money. STFU and come play Super Mario Bros!!!"
I'm just suggesting a lighter, more direct, and less bullshit infused approach.
