Ha! Your question made me laugh. It's a legitimate question--it just cracked me up. I could picture you sitting there drinking a cocktail and rolling your eyes while your date chugs on a Mike's and gnaws on hot wings.
I don't know if it's wrong, but we all do it, and not just with liquor. If you're at a ritzy restaurant known for its wine selection and your date orders a Bud Light, it's hard not to look down your nose at him. I suppose a man's beverage preferences say something about his maturity and sophistication, but I've also learned firsthand the dangers of judging a book by its cover.
This is the kind of thing I would file under minor annoyances or pink flags, small things that make you wonder about compatibility but aren't necessarily deal-breakers, like bad shoes or cheap cologne. But then, everyone is different; these things might be deal-breakers to you. If so, that's not wrong. We all have preferences. But I would still advise you not to jump to conclusions based on one miscue. Wouldn't it suck to toss aside a truly good guy just because you think hard lemonade is lame?
Thanks for the question.
