That character was such a Dirty Capitalist. He had his own personal bourgeoisie revolution by overthrowing and subjugating the dying aristocratic store owner in Castle town. And how did he repay Link, the guy who helped him get to the top? By giving him a discount on some overpriced gaudy armor that will still drain all your money if you wear it. When the money is gone, the armor loses it sheen and it does nothing but weigh Link down!
