We seem to be existing on different planes of reality because your arguments are incoherent to me. So my description of the crowds is ridiculous because... that's your experience at Seattle stores as well? Huh?
Yes, that is my experience from non-holiday, non-release weekdays, in the middle of the day, even. I work nearby so it's easier for me to get to the store than it is to get through it. I was there last 3-4 weeks ago, probably 3pm on a Tuesday or something, and it was bad then. I'm sure you can relate, with your understanding of why the Seattle University store "is to be avoided at all costs" and that "there is no worse place to be" than the Seattle stores on holidays and weekends.
Think about your highway analogy for a moment, because it also doesn't work. What is the "it" that they are trying to build their way out of by building bigger stores? Demand. Even if you can't build big enough stores to satisfy demand, why on earth wouldn't you build them as big as you can, anyway? Why on earth shouldn't Apple build their "Museum of Waste"? And if they can't build them big enough to meet demand, how is it wasteful to build the one they are proposing?

It's not like Apple has any customers or anything.
