One thing I'm adamant about is beer. I won't drink beer from big national breweries like Bud-Miller-Coors (BMC). Their offerings are just so pizz-poor, even when they buy out a craft brewer, they end up effing that up as well (looking at you, Goose Island...😒).
The closest to that I'll drink is Sam Adams. They're probably the biggest of the "craft" brewers, but they pale in comparison to the big three. They brew interesting varieties, and a good portion of it is brewed right here in Cincy, so it's a local beer for me.
I was sat at a bar a few years ago, about to order my first beer, when the bartender set one down next to me without my asking.
"What's this for?"
"Private party in here earlier, we're still finishing the keg, so it's on the house. Coors Light."
I thanked him and pushed it right back and ordered my regular.
On the one occasion we hosted a party, one of the guests brought a 24-pack of Busch. Quite rude in retrospect, but I was fairly well lit on gluhwein, but upon leaving, I handed it back to them, thanked them again, and as nicely as possible, told them "No one here is going to drink this, you may as well take it back."
Weird, they never spoke to me again!
