When I started my first job at a grad scheme some 15 years ago, on the first day, we were asked to introduce ourselves to the group and say what name we'd prefer to be called by. This one guy says: "My name is XXX XXXXXXX. I don't care what you call me, just don't call me Ziggy... I HATE being called Ziggy".
This reminds of lord of the flies: I'm not a native English speaker, and only read it recently. When Piggy says he doesn't want to be called Piggy, I figured that's what he would be called the whole book. Alas, he was, and I cannot remember his real name.
I heard Ziggy still works there.
