We had it at my cousin in laws Mexican restaurant. They are closed on Sundays so they did it special for him.
The choice moment came near the beginning when my dad stood up to welcome everyone and thank them for being there.
his opening line was "Welcome to my pre-memorial service." Everyone just about fell off their chairs.
I didn't see one person get up to go smoke the entire time but, I met many who have lost husbands, fathers and mothers to smoking.
