What's wrong with asking someone their 'first' name?
well my "first" name is Andrew. I don't use it, nor does anybody in my family when talking/referring to me. And it's common practice in the rest of my family to use one's "middle" name.
Mind you, if you knew what my uncle's 'first' name was, you'd understand 😉
What really pisses me off, though, is people that don't know me call me by my "first" name because that's what they assume I'm known by. Don't assume, it leads to f*ck ups.
Especially those people that are trying to sell me something. "Mr Drummer to you please"
