He writes, perhaps only a little tongue in cheek:

What would be the welfare gains if we banned customers from talking to the sales clerks, and vice versa? I find that at least once a week I am frustrated, waiting in line, while the customers and sales clerks chat merrily. They don't seem to care. They don't know how truly important *I* am. They think their little conversation means something in the broader scheme of things.

And he has an ingenious idea: don't tell people where the secret blog is unless they buy his book, which I did before he announced this scheme, and which I am eagerly awaiting. It will be interesting to watch the sales rank climb.
