Their are plenty non ridiculous examples, but no clear place to draw the line. What if I asked to be addressed as "Sir"? Would it matter if I were nobility, or a nobody just trying to assert dominance? Or if you hated me and thought I was the opposite of a gentleman? But what if I thought of myself as a perfect gentlemen? Are you bound by my self perception? Ridiculous is a relative term. If I think a request is ridiculous, am I free to ignore it?
