When you are at a large party like a wedding, say ten people per table, do you worry about everyone being served before you start eating?

Just wondering. I am pretty sure the etiquette is you are not supposed to wait. Although most catering paces and hotels would typically do their best to serve everyone at a table at once.

Sometimes a cold appetizer or salad is already at the tables as you are seated and bread is on the table. Would you just go ahead and sit down and eat, without worrying about the rest of the table, not knowing when people will get to the table, or if the table will even be full?
