This fish market is right next to my morning frequented cafe. It is one of those places I know by passing in front of it so often. I know they sell fish, the front window is decorated with catch of the day on the bed of ice. I know the place is well maintained, every time I walked by it I was not hit by the typical smell of fish market. So I know they sell fish, shrimp, crabs, oyster, even sauce for cocktail shrimp. I know the two neon signs they have up there. I know the delivery bikes they have lined up in the front sidewalk. I even like to stand right at the corner in front of it and take pictures of local characters walking about their morning. So I know this place. From the outside.
I never went in, curiously I was never curious about the inside. My mental image of what going on inside is based on my assumption. How often do we do this, how much of our knowledge of a place is based on assumption?
