For me this is by far the main reason. I do eat out, but only at a select few places. Pretty much everywhere else, I end up thinking that I could have cooked a much, much tastier meal for a small fraction of the price.

I think more and more places are capitalizing on people who don't cook. A local bakery is all about giant cookies. I bought some once and almost gagged. They are clearly made using vegetable shortening and I have to assume their customers can't taste the difference between that and real butter. Really, I'd happily pay the small difference if they used high quality ingredients. The places that actually care about the quality of their food and not just their profits are the ones that get my business.
