Past, present, or future- it doesn't matter. People need to eat. Suggesting that people just don't go to restaurants is as helpful as suggesting people just don't go to grocery stores. That's why this fact:

restaurants hardly ever list their recipe as it is proprietary.

is doing a great job of convincing me that it is actually impossible, and if I'm honest you've said nothing to convince me otherwise. I think that's the disconnect.

I'm not going to stop going to restaurants. Don't get me wrong, I hate Nestle as much as the next lemming, but restaurants are not something I'm ever going to be able to cut out of my life completely. And I'm willing to bet my life on this being true for a lot of people.
