What method do you use for selecting a rotisserie chicken?

I've seen what I can only describe as a wide variety of methods. From rapid drive by grabbings to entire family discussions that last a few minutes.

Personally I just look for any that are touching the top plastic because to me that means "big enough.". Am I being too simple? Is there more to it? What is the "art" of Costco rotisserie chicken selection all about?
