How close does one need to be to say a Bracha over the havdala candle. One doesn't have to put too much effort to get a candle for havdala. Returning to the place you ate to bench. How long one has to bench after finishing one's meal. Saying amen after just hearing part of a Bracha or the Bracha of a child. Saying one's own bracha even if cam just say amen. Having clean hands for benching.
