In practice you're right, i call people what they indicate their designation to be. Where I work we've had a person call themselves something like "Grand Wizard-Admiral of the Terran System" - some people like a pompous name.

If a person is an MD, professor, and such then that's totally acceptable. If the designation is "the Queen says you have to call me sir now" I don't really see what business it is of the Queen's or that it's more respectful to recognise a person because "the Queen smiled at them" than recognising their actual work/effort as fellowship of a learned society does.

It's an anachronous system of nepotism; bleurgh. What's not to like./s
