I was home for lunch today and laughed out loud at the memory of this event. My brother is rrrreal funny, and likely completely unrelated to that, funny things happen to him often. This was in Roswell, NM, right outside of a WalMart that happens to be in a mall there (?!?).
Stranger: Hey, where can I find printer paper?
Bran: Oh I'm sorry, I don't work here.
Stranger: Like the kind that you just use in a computer printer.
Bran: I'm sorry, sir...I don't know what to tell you...I don't work at WalMart.
This came to me while I was taking out the trash, and I laughed and laughed.
