The differences I see between the two. Your pet store is quite a bit larger. It's better lit. It doesnt use glass tanks or wood shelving, and the floor is whitish. They dont have as much merchandise displayed.
None of that means I think the Chicago house is better or worse, cluttered or dirty. It's just merchandised and laid out entirely differently.
I think without you seeing the shop in person, cant really say it's terrible right?
