5. Let someone tell you about THEIR beer experiences
You might not give a fuck about the Chimay Red that someone is quite happily downing for the first time, but that's how talking works -- you listen, then respond. Think about other conversational contexts. When someone tells you about their baby shower, you don’t try to outdo them by saying how yours was really obscure and you had to trade a case of Heady for the wall decorations. Beer should be no different. When people encounter beer nerds in the wild, they are subject to a railing diatribe about all the releases, trades, and bottleshares they have attended. That isn't fun for anyone, especially if you have no frame of reference for what the other person is talking about. Know your audience and listen to an ENTIRE story about a pumpkin beer that someone else loved, even if it makes your sand-dollar nips all achy.
6. Spending more on a beer doesn’t make your beer story any more relevant to the average person
Whenever someone even mentions a beer, some snobs’ impulse is to soapbox about better versions; how they've had a more limited version of person one’s peasant-like endeavor. This is the equivalent of a trust fund dipshit peppering everyone else's travel story with how low-orbit flights are getting way too pricey but they’re gonna keep doing them anyway. We get it: this is what you do with your expendable income. Let someone else shine a bit and be proud of some smoked Vienna lager they had while studying abroad. Listening to a two-minute story won’t seal your urethra shut, you'll get through it.
7. It’s perfectly fine to let someone order whatever the fuck they want
If a horrible beer snob goes out with a group of people, chances are they will alienate them by directing the conversation back to beer. "Funny thing about failed IUD devices is, it’s kinda like brewing..." Don't make matters worse by scoffing or presenting officious ordering advice at a bar or restaurant. If someone wants a Shock Top over a 25cl pour of Avec les Bons Voeux, then leave them alone. If they actively ask you what you ordered, of course, then by all means, bother them to your overworked heart's content.
