As both a giver and receiver of PAs, and this being a thread in which the OP asked for thoughts on the matter, I obliged.
What did you do?
How odd, as a giver and reciever of PA's myself I don't feel obliged to go into the cockpit and give whoever is making the PA a brief on how I wish it to be done. As I do not have the ability to influence what or how it is said I will leave it up to the individual.
I then decide what parts I wish to listen to. I always pay attention during the emergency brief however out of courtesy to the crew.
