Is it normal to just down the wine before kiddush, or the eucharist?
I'd never been to a synagogue before, and I thought the service was over so I didn't know why they were giving me a tiny cup of wine. I just downed it in front of the entire congregation, then realized what I had done. Fortunately, Jews don't believe that God is actually in the wine.
Is it common for guests at a religious service to misuse the wine like this? I think it's funny that the only faux pas I made the entire time was the most obviously avoidable.
