The milk is still in the back, along with perishable juices. The difference between them and the aisles is that processed foods (frozen dinners, vegetables, snacks, brand name yogurt & cheese, ice cream, breakfasts) are all located near the front of the store, while fresh ones (milk, meat, fish) are located at the back, and perishable-but-non-refrigerated goods (fresh fruits & vegetables) are off to the back & side. So it really seems like a deliberate attempt to put the items you would buy frequently as far away from the door as possible, and make you walk through the goods that you might stock up on on impulse.
