These questions are missing the point. The person you're talking to has no control over the policy so any response directly to them is not going to impact that policy which means the objectionable nature of the policy and your desire to change it are irrelevant. If you're so deeply offended by the question, either stop patronizing the business or voice your criticism in a more constructive manner like trying to reach out to corporate or organizing some consumer action. Don't go the easy and lazy route of attacking the messenger.
