Inside the building, I reserve a carrot cake every week from that baker on the west side ( who is from in-town ), sometimes get sausages from those people at the south east corner, have bought veggies from many of the vendors, and pick up maple syrup for my Mum in England. The wild blueberries are very good no matter who sells them.
There's a different sort of sidewalk etiquette inside the building. People are slightly less ruthless.
