Heh. Yeah, the main mall in downtown Portland has three Starbucks. Two of them are quite literally on top of each other. One on the second floor, one on the fourth. They could drill a hole through the third-floor (non-Starbucks) store and pass stuff to each other. Plus a few non-Starbucks coffee places, of course.
On another corner in downtown Portland there are three coffee shops (one a Starbucks) on three of the four corners at an intersection. The fourth block has a coffee shop in the building, rather than on the corner. What, you can't cross the frickin' street to get your coffee?!
(Then again, when I worked for Intel, which had a Starbucks 'kiosk' in the cafeteria, the coffee lady knew me so well that she'd have my Mocha just finished and waiting for me when I showed up at 10:00 AM every day. Damn, I could have doubled as an atomic clock.)
