I've done some of their larger stores. Longest it's ever taken was 1:45. This is another of those projects that you treat like a Kmart audit...do the perimeter of the store first in the order that you come to the departments, NOT in the order they appear on your paperwork. Go in a counter-clockwise direction. At that point you'll end up at frozen foods and then the center of the store. Also, when doing the center of the store, walk down the center of the aisle, look and count one, four-foot section, then turn your head to look at the section on the opposite side and count it. That way you're only making one trip on each aisle.
