I can only speak for myself but I've eaten at Michelin star restaurants all over the world and enjoy fine dining whenever I have the time and I love it, but sometimes I just want taco bell.
Alcohol, on the other hand; good Scotch and wine has ruined the cheap stuff for me. I can't drink cheap, or even mediocre, whisky or wine anymore. If it's not very high quality I'd rather just have something like a gin or vodka cocktail.
Absolutely, I shouldn't have used cheap as a synonym for bad, or vice versa, that's my mistake.
There are a lot of very good wines at low price points, especially from underappreciated regions. A little experimentation will result in finding some great value.
The same goes for the whiskey. There are a lot of distilleries out there with great offerings far below the price of the big names everyone recognizes. Especially when you take fads into account. Many bourbons and Japanese whiskeys that used to be good buys are now ridiculously priced.
My parents had decent taste and decent money when I was a teen. My first interactions with alcohol were expensive wines they were willing to give me a taste of and some expensive liquors I siphoned out of. I am now broke and all the liquor I can afford sucks. Their desire for bourgeois decadence ruined my college indulgences in cheap liquor.
