As Mike says, you have to entertain yourself to be successful in this business.
They do a great job of that. Building from thief relationship and their relationship with others and bringing in people that they share a common thread with and simply having conversations about things that matter, things that don't and having a blast building this larger interconnected community of people from many walks that share some common thread.
I grew up in a small SC town in the late 70s and 80s. A time when most everything closed at noon on Wednesday & Saturday and didn't open on Sunday. My dad and grandad owned the hardware store in town, that had been the general store since the 1880's. The barber shop next door, the gas station on the corner. But their store and the bench out front was a town gathering place. They with people they knew well and people that wandered up and they happened across, they did what Mike and Chuck do here. They had conversations, built community and above all entertained themselves in a way that made others want to be a part of it.
They're was a barber shop, but no quartet, though they'd all have appreciated that deeply and I do think that an outbreak of singing would have been genuinely appreciated.
