“Popeyes Fried Chicken” should be “Popeye’s Fried Chicken.”
According to the “Popeyes story” at http://www.popeyes.com/story.php, the restaraunt was named after the “Popeye Doyle” character in “The French Connection.” Since there’s only one “Popeye Doyle” character, the ‘s’ in the company name *must* be the possessive s, which means that the chain’s name, registered trademark, and every logo on thousands of signs and boxes and menus and letterheads for “Popeyes” is a case of incorrect, missing apostrophe.
That would indeed be a staggering case of abuse — if it were true. You see, Matt, the “Popeye Doyle” back story is just a ruse! You’re really eating at a restaurant called “Pope Yes“.
