NT's local Morrisons has one aisle devoted to "Dog Food" and "Lightbulbs", which is an interesting combo.
They also have one marked "Chocolate Biscuits" and "Healthier Biscuits"....
My local branch of Mr Sainsbury's Emporium of Toothy Comestibles had "Everyday Treats" and "Special Treats".
Mind you I boggled slightly when I parsed the sign for "Loose Passion Fruit" wrongly.
And as for "Adult Cereal"...I haven't time for that sort of thing in the morning. (but I do wonder what it involves).
