I own a small contracting company. We sometimes, for purposes of goodwill, pay for things that weren't our fault. But it is our choice and for our advantage if we decide to do so. If we refuse to go above and beyond the contract for a customer he was not wronged.
Sometimes when we choose not to go above and beyond it was because the customer drove an extremely hard bargain in the price negotiations. Or he was a general pain in the ass to deal with and we don't care if he comes back. But we do not wrong him when we decline to comp some cost over and above the deal we made.
Several years ago my dispatcher bought a new car over a weekend. On Monday morning the salesman showed up at our offices with a bouquet and a cooky basket for her. I winced. When I buy a new car I hope I made such a good deal that the sales manager will be standing on the parking lot giving me the finger as I drive off in my new car. I don't expect a lot of comp after I make that deal. But if I don't get it I wasn't wronged.
