I can guarentee that he didn't use the pre-prepared stuff (other than jams etc) as his son attempted to re-start the business and wanted to use such means. Johnny wouldn't hear of it and personally went down to bake the "proper" way

The son's heart wasn't into it, so that shop is closed now too.
I'm sure your cake was awesome! Mine was from Montilio's and it was beautiful as well. Let's not open up the Konditermeister can of worms here, LOL.
With all due respect, I understand your point, but I suspect you aren't aware of how bakeries actually operate (as most people aren't). You make it sound like the bakery closed because the son used commercial products. While it may appear that way on the surface, in fact there's generally a whole lot more involved than that. The baking world changed in the years between father and son running the bakery. Let me explain.
There are many reasons why it's very hard to find small bakeries any more. Costs are a huge factor. It's not uncommon for bakeries to have monthly utility bills of several thousands of $$ from the costs of running enormous ovens, proof boxes, freezers, walk ins, mixers, lighting, etc. Just to pay the utility bills they need to sell an enormous amount of products, and/or keep prices inflated. Then you have labor costs. Bakers, baker's helpers, decorators. As anyone who bakes things knows, it takes a while to get a nicely finished product. Multiply this times hundreds of dozens of things: you have prep and mixing time, panning time, proof box or refrigeration time, baking time, cooling time, slicing and packaging time, etc. A wedding cake can take anywhere from two to six hours just to decorate - baking it not included. It's not unusual for a bakery with a large cake business to employ several full time cake decorators.
Packaging is a whole other ballgame - regulations now require ingredient labels on anything packaged, and nutritional information in certain states. The packages themselves cost a small fortune, and don't forget paying the floor staff, cleaners, manager, exterminator (!!

), electrician, refrigeration mechanic, maintenance person for the machinery which constantly breaks down, and on and on. So bakeries have to charge a lot more for the pie when you can just walk into BJ's and get a similar pie for a lot less. Some people prefer to buy a bakery pie and for good reason. But many more people would rather get the pie (and name any other bakery product) somewhere like BJs or the supermarket due to lower cost and convenience (for what many times could be virtually the same product

). That's a fact of the industry. Small bakeries can't compete anymore. Of course, you can still find some around, fortunately, but many have closed. Those that are still around often struggle under the costs today; at minimum, they don't enjoy the high profit margin that they did in years past.
I don't want to belabor the point, but commercial flours and mixes are the industry norm, and have been for decades, as you can see from a couple of the links I've posted. There is not a bakery around that doesn't use at least some. That nice little Italian bakery you walk into that offers "old style" bread? It more than likely has at least some dough enhancers, conditioners and preservatives in it - otherwise it would be like a rock and last about a day, which is not what most people want (think: suing the bakery for the broken tooth; "better" breads have a nice crunch on the outside and are soft on the inside, and will last a few days - thank you Puratos S500
http://en.puratos.co.jp/products_solutions/bakery/bread_improvers/s500.aspx). Even companies like Whole Foods use organic mixes now. Once again, it's the norm. Next time your driving down the highway, take notice of all the baking supply company trucks on the road - they're everywhere. And again, they're not "bad". In fact, they've helped improve products tremendously, and everyone - yes everyone - is using them at least to some degree.
My two cents for the day. Sorry OT mono~rail. Carry on...
