Revisit the opening short case in this chapter that examines some of the principles behind supermarket layout. Then visit a supermarket and observe people's behaviour. You may wish to try to observe which areas they move slowly past and which areas they seem to move past without paying attention to the products. (You may have to exercise some discretion when doing this; people generally don't like to be stalked round the supermarket too obviously.) Try to verify, as far as you can, some of the principles that were outlined in the opening short case. If you were to redesign the supermarket, what would you recommend?
