i could be completely wrong on this as i am in no way any form of legal trained, but i am pretty sure you cannot be held liable for any of the above due to the fact that you’d be considered a third party and you did it without prior knowledge

Fortunately, I've already opted out of delivering alcohol. I just didn't want to think about the possibilites of that as I had to actually take an online test for it and the scenarios were going through my mind. Moral is, if you're not comfortable with anything you don't want to do, don't do it.
