Nope! It's a real thing. Also, a butler calling their employer "master" is inappropriate if they're not a child.

Take for example: Bruce Wayne and Alfred Pennyworth! Alfred *should* be calling him Mister Wayne, based on proper etiquette. However, since he raised Bruce he has continued calling him Master Bruce as he did when Bruce was a child.

Yes, the example is a butler - that's because being a genuine butler is still a very serious profession. There's specific schooling for it, and part of that schooling includes formal speech and formal methods of address. It was proper to call the young master (a son or sometimes younger sibling of a household) "Master [name]" and only the head of the household would be "Mister [name]"

The average person doesn't use formal methods of address anymore as it's fallen out of fashion.

That's actually kinda cute I didn't know that's why Alfred kept calling him Master. That's still his boy
