Scrap Gold And A Haircut, Two Bits

I saw these sign recently when I was in New York.  Feel free to click the picture to enbiggen but that really is a barber shop that wants to buy your gold.  I've seen a lot of business combinations that don't make sense but this one ranks up near the top of the list. I wonder how that transaction would go: "Hey, Mike!  Just take a little off the top and here is my old wedding ring.  Keep the change."
