Everything you need to know about honorifics and cultural differences you can find in Japanese Maid Cafes:  What you find is that some in Japan revel in the idea of servants and desire to be given titles of honor and status they don't deserve.  In American we desire neither and see both as hated relics of the days of slavery in our country before our Civil War.  We now conceptualize only employees and whatever they have signed on to do.  And the only titles of honor we use are Doctor and those of elected officials, all titles of merit.  Japan still stinks of it's feudal roots and still has got a long way to go to catch up to the 21st century.  Use or desire for titles of 'Master' or 'Lord' will get you a punch in the face here.
