This is interesting -- we know grocery stores generally keep their whole foods around the perimeter of the store. One of those foods--milk--is almost always placed the maximum amount of distance from the entrance...apparently so you won't stop in only to buy milk. This is definitely true of the three stores I most shop at for sure--Ballard Market, Central Market, and the Holman Road QFC. And I can think of other places where this is true too: the Crown Hill Safeway, and even the 7/11.
From the Notre Dame website page on grocery store psychology:
"Grocery stores stock the items shoppers buy most often at the back of the store, forcing them to travel through other tempting aisles to pick up the essentials. Items such as meat, eggs, dairy and bread are strategically placed in the back of the store, making it hard for shoppers to resist grabbing other items when making a quick trip to the grocery."
