"I love excellent X, but will (or won't) enjoy lesser quality X"

Booze of all sorts.

I’ve tasted Petrus. I drink Black Box Malbec.
I’ve had Gold Medal beers that have been aged in Gold Medal bourbon barrels. I’ve been known to drink Mickey’s.
There’s a bottle of Pappy in the back of the liquor cabinet. This week I was pouring Tin Cup into coffee mugs around a campfire.

OTOH, I won’t go below El Jimador or the like in my tequila, not even as a mixer. (Confession: I ran out of El Jimador, so the margarita in my hand was made with Don Jose Reposado.) I’ve also eaten at world-class steakhouses, and have gotten rather spoiled. To the point that I’ll order the chicken instead if I’m not at one of my favorites (Delmonico, CUT, SW Steak, Bazaar Meat, STK).
