Not really. The shop could've made a little extra money by selling him what he wanted at the price he wants. Instead they made none. Their operating costs stayed the same. Not serving him was a poor business decision on their part, but well within their rights. The retail model is only in trouble if everyone starts doing what he is, but I doubt he's going to start a trend. If the choice is between an extra ten bucks toward your bottom line of nothing what do you choose?
