When one makes kiddush for others should he drink first and then pour (so as not to delay between the bracha) or pour for other first and then drink (not to offend anyone with ‘hygenic issues’).
In a non-family environment, one should pour first and then drink. Even in a family environment, this is fine, though one can also drink first. Note that if one drinks first, the cup becomes pagum, and one should not pour out of it for others before “mending” the pegam by pouring a little more wine into the cup. Alternatively, the cut can be handed round for drinking from.
