A mode of behaviour occurring on the behalf of a retailer when dealing with a particularly bad consumer; disgust is being thinly veiled by overly contrived politeness. The seller is quite obviously making it clear that she is barely containing heself from going at said customer with an axe. Example: No, I didn't misunderstand. We just don't sell sport books or give discounts for no reason, the bookseller said policitly.
