Well done. I'm glad that all went well. Sounds like the conversation was working out and it just went there.
Don't feel bad about your dad's beers - they don't matter to him in the same way they would an alcoholic, and he obviously wants to demonstrate his support and solidarity. He might even be seeing alcohol in self in a different light. He's likely feeling a little impotent to 'Do' anything at the moment, so that little gesture might make him feel better (more better than drinking the beer would anyway).
