The manga section at the Border's here (RIP

) was always full of teenagers reading. I don't recall ever seeing one of them buy anything. But not just teenagers. There were always at least one or two guys in the history section reading books they never seemed to buy, either.
And then there was the day I overheard one of the local bums telling another one how he always walked out with a book under his jacket after using the restroom. (I did tell the clerk about it and was able to give her a description. She said she knew who I meant. I never saw the guy near the store again.)
