I've been eternally spoiled by growing up with a grocery store that had a "toiletries" aisle; that's my "feel" for where those things should be. Once I moved away, the idea that I may need to go to the other side of the store go from the toilet paper to the toothpaste seemed like madness to me. Still does.

^(For anyone as confused as I was, most grocery stores keep toilet paper in the "party" section, apparently the logic being it's smaller paper towels/napkins; and toothpaste in the "pharmacy" section, apparently the logic being if you want toothpaste, you must have tooth pain, so it goes by the pain killers the gum-disease vitamins.)
