Standards, like many things, vary with individuals. While I believe beauty is in the eye of the beholder I also believe that a marketer/seller of a product, who expects to be paid for that product, has the responsibility of rendering the product as advertised. If the actual product differs from the product advertised/marketed, it is the buyer's decision whether or not to accept and pay for that product. Some buyers are flexible with misrepresentations, some are not (for some buyers paying $300 and up/hr is not an issue, for others it is a special occasion).
In this regard, I can accept a working guy having age, weight, race or other restrictions if those restrictions are clear in his advertising. It is "down right pissy" for a working guy to inflict humiliation upon an unsuspecting prospective client at the door (as I'm sure you know, this issue has been done to death in prior threads).
Lastly, it is the buyers that set the standards of markets. If it becomes the case where the general practice is buyers accepting and paying for whatever misrepresentations they are given, standards will fall, whether the product is for the bedroom (or the Oval Office).
