(The store in question was very small: eight aisles, total, in a nice, easy-to-see square configuration.)

Customer: “Where are your batteries?”

Me: “Aisle 3.”

Customer: “Where?”

Me: “Aisle 3…” ¬†*points* “… just behind you.”

Customer: “Oh. Which one is aisle three?”

Me: “The one with the ’3′ on it, sir. ¬†In between aisles two and four.”

Customer: “Thanks!” *wanders off into aisle 2*

Boss: “Don’t do that again.”
