I really like what PanchoHambre said, well said! I also think GB stated it pretty clearly and concisely as well, a snob thinks they are a better person than you because they can do something better than you, or have something you don't have, etc.
Other than that, I say put your money where your mouth is, so I can put your food where my mouth is! Even if you are only half as good as you think you are, I still win! LOL. I love all food types from down home cooking to top notch chefs and their restaurants, but my comfort zone is definitely with the down home cooks. Not because I think chefs are snobs, but just because I can relate better with down home cooks. And quite honestly if the chef is going to cook for me, I would fail to see the downside to them being a bit of a snob over their ingredients...
I just try to keep an open mind.
