Dude people give adult beverages to the adults walking their kids around in every neighborhood. It's not a big deal. They're not handing beers to toddlers.

I dunno, I think parents handing out alcohol to other parents on Halloween is one of those fun things that makes neighbourhood friends.

It's hard to make new parent friends so it's a quick vibe check and a friendly offer to some parent who has walked very slowly, has a sore back from crouching down and holding hands for a couple of hours and knows there will be a battle about candy distribution later.
