Customer: “Do you sell leather-scented candles? Or a leather incense?”
Me: “We do not.”
Customer: “You don’t? Then where is that amazing leather scent coming from?”
Me: “It’s… it’s from all the leather.”
Customer: [looking around] “Oh, hey, wow! I never noticed that before!”
It is generally accepted that when one sense is diminished, the brain rewires itself to draw more receptive information from the remaining senses. In this case, I can only assume that said customer lost his eyesight in a tragic, comic book-style accident, which gifted him with a preternatural sense of smell… and, I don’t know, maybe super strength or something? I wasn’t there. Long story short, he should really just get out there and fight crime.
