I think they should try to make it so people get their food together. It's not at all uncommon for one person to want to wait until everybody has their food, which usually means you have six people staring at their food getting cold while one person is waiting.

If they order something that takes twice as long to cook that's a different story, but in most cases the kitchen should be able to get stuff to come out about the same time.

For the same reason, I hate it when they pick up my empty plate when other people are still eating, I feel it makes it seem like I am rushing them or something.
