How does one proceed at a Kiddush where the one making Kiddush can sit down but everyone else stands? The cake is not covered before kiddush. In every case attendees make a brocho before eating or drinking.
I have seen three modes of behaviour:
Attendees have nothing in their hand until kiddush is made and then take and eat cake.
Attendees take a whisky in their hand until kiddush is made and then drink it.
Attendees take cake and a whisky in their hand until kiddush is made and then eat the cake first.
1) Does the halocho allow you to partake of a kiddush standing? (After all a seudah is normally eaten sitting and we need kiddush in the location of a seudah).
2) Is it right to hold the food in your hand before kiddush? (The one making kiddush makes a brocho on wine; we normally cover bread in this situation.)
3) What should you partake of first?
