The Guv'nor.

One of the many everyday social changes that George Orwell noted about revolutionary Barcelona was the dropping of formal forms of address. I hate being called "Sir" by shop assistants, not least because of the very obvious insincerity. Respectful forms of address don't necessarily imply hierarchy and subservience I suppose. It can just be an acknowledgment of respect between equals. I am of a generation who would address male strangers as "chief" and I am now of an age when  I get to be called "Guv'nor" occasionally. Truth be told, I quite like it.
