Window seat.

Before I attempt to grocery-shop, I've determined that it's in my best interest to feed my toddler. Otherwise, he is given over to the devilish way of stealing fruit with hungry restlessness. I usually buy him a sandwich in the little restaurant situated right inside the door of the front lobby, and I enjoy sitting at the same table each time. A window seat. Only the window seat doesn't allow one to observe the outdoors--instead, it's a front row seat to watch the looks on peoples' faces when they set off the walk-through alarm. If you really want to experience the gamut of human nature, examine the faces of people who are suddenly feeling accused, with or without merit.
