Re: serving alcohol
I feel sorry for people who dont understand hadiths, and think Quran is understandable on its own. You must have some twisted logic to support that claim.
I always found haidth rejectors to be the narrowminded ones, with lack of knowledge. They always start to contradict themselves when you ask them to give you verdicts from Quran, or to elaborate a point from Quran. They go speechless.
Regardless, Serving, trading, manufacturing, and drinking, wine (which btw has alcohol in it, 
) is HARAAM. And should be avoided.
