I am a snob about several things and not ashamed of it. When I say I'm a snob about e.g. coffee, I just mean I'm picky about what I choose for myself and have high standards, NOT that I'm rude- if I'm at your house and you serve Nescafe I'll accept or decline it with a "thank you" of course, and no commentary or opinions. I believe this sort of snobbery improves one's life. I used to accept things I didn't really want out of politeness etc. or feel obligated to go to an event I'd rather avoid; being comfortable saying "no thank you" is quite liberating.

THAT SAID, it amazes and disgusts me when people treat being a snob as some sort of accomplishment. "Oh I'm really picky about coffee... I just know a lot about it and blah blah blah \smirk\." This is no accomplishment and not something to be proud of.
