The smartserve course was an online one well before COVID, so really had nothing to do with it.
I don't think it's pointless though; as
@Halifax Tar pointed out, the ships have a NS liquor licence, and I'd rather have a check in the box than lose the privilege all together if they crack down on it. Having those kinds of checks in the boxes is helpful when making the argument to not go hard over with a group punishment.
People acting stupid is a universal constant, and common sense isn't, so frankly I don't really mind having to do things like that as it is a genuine surprise for some people. The reason we keep talking about this kind of stuff isn't because people are doing what they are supposed to.
For the weirdroom, I'm personally a fan of a bartender, as otherwise the chit book just goes to a complete mess. We usually had (legitimate) volunteers for actual events, and then someone did it adhoc outside of that. For small groups just having a beer or whatever it tended to be whoever happened to be standing behind the bar, so really just talking about parties etc.
It's really simple to do, so surely it's not hard for the great and mighty brains in the Wardroom to take charge and show a bit of leadership to figure out. And while we call the ship our home, it's not, so just because we can ignore a provincial law with no likely consequence, always ask if we should be. Similarly, there are OSHA and WHIMIS standards for a really good reason, and especially during peacetime, no reason we shouldn't meet or exceed them. We're supposed to be professionals after all, and professionals have rules and guidelines.
