I'll drink Maxwell House or whatever, but I won't enjoy it. Given how much coffee I drink--I tend to drink between one and two 10-cup pots over the course of a day--a couple bucks more for a nicer brand is worth it.
I would never consider myself a scotch snob, but I can't drink Dewar's or the like anymore. I'd rather have my favorites every few months than a cheap brand more frequently.
Everything else is negotiable. If I had to do a blind taste test of store brand vs. name brand salad dressing or whatever, I probably couldn't tell the difference.
All that Nabob, Maxell House, Folgers, etc. coffee is swill IMO. To me it's not even coffee, it's just **** flavored water.
Breakfast in Bed by Wolfgang Puck are really tasty k-cups.
I'll also say that I enjoy good beers. I try to only buy local San Diego beers for my everyday type beer. When I treat myself to a new beer I usually don't care about price, so long as it's not like $20 for a sixer.
Not a food snob for too much here... back in Brazil, if I had soft drinks, it had to be Guarana Antartica, or Mate Couro. Oh wait - I almost never have ice cream, especially vanilla, but if I DO have vanilla ice cream, the generic stuff is crap.
But I'm a food snob in general. I go to the market for everything whenever I can.
What kind of tea you normally get? Right now I'm stuck on a citrus green tea from Teavana.
I'm the same way. I go to the gym most days after work, and it's in the same strip mall as the grocery store I go to... and even if I don't, it's less than a 1/4 mile away and a 5 minute walk. So I'm pretty snobby with having fresh produce, and will refuse to eat canned goods of any kind, and usually don't have to get frozen unless I want something out of season.
