If you’re going to be a dick to brewery staff, stay home.
If you’re going to argue about the rules, stay home.
These things are entirely out of the hands of brewery staff and attempting to give them any sort of shit about it just makes you look like an asshole.
Sadly this behavior isn’t unique to Urban Growler Brewing Company. We’ve heard of similar situations at other great breweries as well. Knock it the hell off.
