This is a pretty interesting video about supermarkets and how they are layed out. While I’ve worked at a couple of retail stores I learned quickly that if you grab a shopping cart you will end up getting more then what you can in for. This can also relate to how Clothing stores are laid out. Another thing I do not recall where I heard if from is that retail shops have mannequins to for people to visualize themselves in the mannequins place.
