This error may be a bit subtler than some of the errors in the other photos. But just because it is not as obvious does not mean it is not important. The problem with this sign is a missing hyphen. Words that begin with prefixes like self- always contain a hyphen between the prefix and the rest of the word. It should be self-storage, not self storage. Take a look at some public signs the next time you're out and about. I can guarantee you'll see other instances of missing hyphens in words beginning with self- (e.g., self-serve).
