The Waste Lands features a bookstore owner named Calvin Tower. He runs a bookstore in Manhattan that's laid out and advertised like a restaurant, except that they sell books. He makes a bunch of references in conversation for fun. He gives a kid two books he prices at $12 at a discount of $7 and sells them gladly anyway when the kid only has $5. He banters with a random buddy he's playing chess with. Calvin says the building would be up for sale if he owned it rather than leasing it, but I don't buy that.
This scene includes a bunch of detail that just didn't need to be there. I'm glad it is there anyway.
