My take on this is if you're on a party and someone introduces himself as a Knight or a Baron, which one would be your attitude?:
- answering "Pleaased to meet you, Sir" and treating him with deference
- challenging him to proof he really holds this title
To keep with the analogy, if you're stopped by someone on police uniform while driving who asks for your driver's licence, which one would be you attitude?
- drawing it from your wallet and presenting it to him, while saying "Here you are, Sir. Have I done anything wrong?"
- challenging him by saying "Of course, Sir, just after you show me your credentials as pocileman"
Again, spoiler: I'd chose 1 in both cases
