"This is the best beer in region" - no sale
"I love this lager, so nice and hoppy" - it's ale, and it's barely got a sniff of hops, which is the actual reason you like it you limp wristed chequered wearing motherfucker.
"I don't drink dark beer" - That's fine, you don't like beer. Fuck off, and for future reference, when you order a glass of Stout, it's going to be dark.
"I've been drinking beer my whole life, I think I know what I'm talking about" - No, cocksnap, drinking XXXX Gold for thirty years doesn't mean you know anything about beer, it means you're a cheap fuck that bashes his missus.
"Just let me take this chewy out of my mouth" - Just let me take those teeth out of your mouth.
You remember the bad, more than the good. The good memories in your life don't haunt you, do they? I get mainly positive people, and people that are 'in tune' with how they taste my beers - if you don't like it, that's fine, I am absolutely cool with that, I have no idea how many beers I've tried and not liked. But to assume that because you don't like it makes it bad is one of the dumbest things humans do, across the board.
