It's one of four things:
(1) Either a dyslexic person is putting up a lot of the local business signs. Or,
(2) Someone hired a 4 year old to do it and thus are in violation of Child Labor Laws and should be imprisoned promptly. Or,
(3) This person is an idiot and should be imprisoned promptly. Or,
(4) The backwards N is a secret code of some sort that involves ground beef, Jesus, and fish.
Chew on that.
