Have you ever heard of the concept of “shuttering”? I hadn’t until recently. During my morning reading, I stumbled upon an interesting Apple News article about Costco closing. My initial reaction was, “Oh my! First Red Lobster, now Costco?” Naturally, the headline did its job and grabbed my attention. It turns out Costco isn’t closing permanently; they’re shutting down for a day of rest, something they call a “shutter.”
