Gentlemanly behavior or etiquette in general at least historically could be summarized to always make the people around you as comfortable as possible. In that way being as nice as possible to the drinkers makes sense, its not like you're billed by the spoken word or something. Also it makes the manager in the linked article a hopeless jackass for making the employee uncomfortable, even worse doing to in front of peers. Well, every continuum has a median and someone has to end up below it... Its interesting that the topic changes but the subject never changes. Everyone expects this kind of behavior with food, now a days. Historically it was normal for religion. You'd agree with your immediate boss or things would get very uncomfortable very quickly. Times change. Maybe someday people who don't drink won't be bullied, much as its pretty much OK to be Jewish nowadays, or whatever else. Another set of current day examples are progressive/left wing political signalling on social media which is fairly mandatory, and strangely enough the ecosystem your phone belongs to (ios, android, or the also-rans).
