It's might sound OT, but it's not. There's a really, really successful hardware store, locally owned, near where I live. Contracters go there, so do do-it-yourselfers, and a lot of folks who just need a garden tool or even light bulbs. It's popular in an era of big box stores and online retailers because almost as soon as you walk in someone is asking if you need assistance and then helps you. They said in a local interview that they don't care of their hires know jack about hardware. They hire outgoing people-oriented helpful folks and teach them hardware.
